Web Developer 1.0

A year in the making, I am plea­sed to finally announce the 1.0 release of the Web Deve­lo­per exten­sion. This release con­tains a huge num­ber of new fea­tu­res and bug fixes.

Some new fea­tu­res to look out for are:

  • Dis­play Ele­ment Information
  • Dis­play Ruler
  • Edit HTML
  • View Docu­ment Size

Other nota­ble new fea­tu­res are sup­port for ope­ning the current page in another appli­ca­tion through the cus­to­mi­za­ble ‘Tools’ menu and vie­wing the source in an exter­nal edi­tor through the cus­to­mi­za­ble ‘View Source’ menu.

Please see the upda­ted docu­men­ta­tion for more information.

If you are upgra­ding from a pre­vious ver­sion of the exten­sion you are strongly recom­men­ded to unins­tall the exten­sion before upgrading.

If you are having pro­blems after upgra­ding you should unins­tall the exten­sion in safe mode and then re-install.

    Keep up the good work! This is an exce­llent tool, although it’s fin­ding too many mis­ta­kes in my designs :( lol

  2. BenJ says:

    More like YEARS in the making. Con­gra­tu­la­tions Chris! Web­Dev is a lifesaver.

  3. Zach Inglis says:

    :) Brilliant.

    ‘Edit HTML’, what with Edit CSS I see Live deve­lop­ment If these fea­tu­res could be added to the top of Fire­fox rather than the side Live Deve­lop­ment would be pos­si­ble. Currently it pushes % off side­ways which make it impos­si­ble to be sure that everythings right.

  4. I am loo­king to improve the side­bar fea­tu­res in a future release to allow doc­king to any side of the brow­ser as well as floa­ting windows.

  5. Gene Kohli says:

    Thanks for your work — Web Deve­lo­per is a great tool. Perhaps the most use­ful tool I’ve found in 8 years of web development.

  6. Thanh says:

    Thanks for the job. :)

  7. JulioNC says:

    Whow.… thx Chris!

  8. Laz says:

    Keep up the exce­llent work!

  9. Keul says:

    The most inte­res­ting tool for my fire­fox, hel­ping me to fix many pro­blem in IE too! I LOVE the “View style infor­ma­tion”!
    The new “Dis­play Ele­ment Infor­ma­tion” works great but, if I can sug­gest, will be VERY use­full if the click on the Chil­dren or Ances­tor ele­ments lis­ted will make something like open the DOM Ins­pec­tor on the selec­ted ele­ments.
    I talk as a dummy-users, I don’t know how this will be dif­fi­cult, but exten­sion like Ins­pect Ele­ment do this, and I find this fea­ture use­full as far as Web Deve­lo­per too.
    Again thanks!

  10. Seba says:

    There are so many use­ful impro­ve­ments in ver­sion 1.0 (Dis­play Table Depth, View Docu­ment Size, Dis­play Line Gui­des, …) — marvelous!

    The BEST exten­sion to Fire­fox — really. And the most impor­tant tool for web­wor­kers, too.

  11. Anonymous says:

    Hands Down, the best fire­fox exten­sion I’ve got.

    Thanks for pro­vi­ding this to the community.

  12. Keul — This is a good idea and I’ll look into it for a future release.

  13. Simon says:

    Holy CRAP. I thought this exten­sion was essen­tial before. Kudos upon kudos to you, sir! This is marvelous.

  14. knocte says:

    If I down­load the loca­li­zed ver­sion of Web­De­ve­lo­per, I obtain ver­sion 0.9.4 ins­tead of 1.0

  15. knocte — This is because the exten­sion was relea­sed less than 48 hours ago so there are no trans­la­tions for it yet.

    The down­load is labe­led as 0.9.4 and I will replace it with the 1.0 release when I have some translations.

  16. knocte says:

    Then me and my l10n group (NAVE: http://nave.escomposlinux.org/) can con­tri­bute. We will con­tact you.

  17. Simon says:

    Fan­tas­tic! Many thanks for such an essen­tial tool for Web developers.

  18. Geir Arnesen says:

    I love the Web­De­ve­lo­per exten­sion. The 1.0 ver­sion, — seem to have a pro­blem when run­ning together with Gmail. I am not able to open attach­ments recei­ved in Gmail. When unins­ta­lling the 1.0 ver­sion, and reins­ta­lling the. 0.94, — everything works fine.

    I miss the “Clear Ses­sion Coo­kies” func­tio­na­lity in ver­sion 1.0.

    Geir A.

  19. Søren T says:

    Hey, this is a great tool, I use it every day!

    –but i too miss the “Clear Ses­sion Coo­kies” — it made tes­ting sites that uses coo­kies much easier. Now I need to close the brow­ser (all tabs) to see the changes

  20. Sweet! I wasn’t expec­ting to finally be able to hover from menu to menu just like that, so that’s a plea­sant sur­prise… wor­king with Web Deve­lo­per just got a bit fas­ter. :) Exce­llent work, Chris!

  21. Milou says:

    An FYI — Fire­fox just noti­fied me that an update was avai­la­ble for your tool­bar. Howe­ver, after I ins­ta­lled it, I had to reins­tall Fire­fox because I lost all func­tio­na­lity of it. I couldn’t type a url, my book­mark tool­bar disap­pea­red, and no home­page pulled up on launch. After the re-install of Fire­fox things seem back to normal.

    I DO greatly value your exten­sion! Happy New Year!

  22. Jens says:

    Thanks a million!

  23. Great work. Well worth the wait. Some of my favo­rite new fea­tu­res inc­lude: Edit HTML, Out­line Posi­tio­ned Ele­ments, View Color Infor­ma­tion, View Docu­ment Out­line and Source and View Gene­ra­ted Source. As a result of the added fea­tu­res I can get rid of nume­rous other exten­sions and bookmarklets.

  24. Kent says:

    Milou: same thing hap­pe­ned to me, but after 3 Fire­fox res­tarts everything wor­ked fine…

    Oh, and thanks for all the work on the exen­ten­sion Chris!

  25. asdf says:

    I had FF1.0.7 english Win­dowsXP. I upda­ted to WebDeveloper1.0 using the inter­nal update tool. All went fine and I res­tar­ted Firefox.

    Then I could do nothing. I could see menus, tool­bar and address field. But clic­king menus or address field did nothing. It was like some hid­den glass was on top of the brow­ser win­dow stea­ling all focuses.

    I could use right-mouseclick to open con­text menu. Reins­ta­lled FF1.0.7 did not help. Wor­ka­round:
    * Star­ted in safe mode: firefox.exe –safe-mode
    * Unins­ta­lled Webdeveloper1.0
    * res­tar­ted FF and all is fine now.

    Other exten­sions I have:
    Dom Ins­pec­tor 1.0, Live HTTP Hea­ders 0.11, View Coo­kies 1.5, View­Sour­ce­With 0.0.7.8, Adblock 0.5.2.056

  26. asdf says:

    Fixed FF1.0.7 free­sing pro­blem:
    * Star­ted in safe mode: firefox.exe –safe-mode
    * Unins­ta­lled Web­de­ve­lo­per 1.0
    * Close Fire­fox
    * Start fire­fox in nor­mal mode
    * Ins­ta­lled Web­de­ve­loer 1.0 again
    * Res­tar­ted Fire­fox and now it seems to work ok.

    So maybe Web­de­ve­lo­per autoup­date is not recom­men­ded, must first unins­tall old ver­sion then ins­tall new one.

  27. Geir — The exten­sion works fine with GMail for me. I would sug­gest unins­ta­lling and re-installing the exten­sion or trying it under a clean profile.

    Geir and Soren — ‘Clear Ses­sion Coo­kies’ is still avai­la­ble, but has been moved to a new ‘Coo­kies’ menu. If you are not seeing this menu then please read the FAQ.

    asdf — I think the auto-update works much bet­ter in Fire­fox 1.5, but if you are having pro­blems please read the docu­men­ta­tion for trou­bleshoo­ting recommendations.

  28. trovster says:

    Kudos. The best Fire­fox exten­sion for any web deve­lo­per out there, it’s a must.

    Howe­ver, the editCSS/HTML seems a lot slo­wer than pre­vious ver­sions. Also, it would be nice to have the option to open the editCSS/HTML in a new win­dow or tab, ins­tead of side­bar, as this res­tricts the size of the site/is small to edit in.

  29. trovs­ter — Please see my pre­vious com­ment about the side­bar. As for per­for­mance, there are no major chan­ges that should have affec­ted the speed — you could try twea­king some of the set­tings for the side­bar in the options.

  30. Dan says:

    I ins­ta­lled the new ver­sion this mor­ning, and now Fire­fox won’t start in regu­lar or safe mode. Any ideas? Do I need to reins­tall everything!?

  31. Matt Sayler says:

    Just a quick note of thanks — WDT is the gold stan­dard for HTML/CSS/HTTP troubleshooting.

  32. Dan — The exten­sion should not be able to stop Fire­fox star­ting in safe mode. Make sure you have no copies of Fire­fox run­ning in the back­ground and then run again in safe mode.

  33. Flack says:

    Gree­tings from Rus­sia :)
    Thanks for a pretty hard job. We all sure appre­ciate this.
    A few notes:
    – it would be nice to inc­lude 1024×768 to the Resize options.
    – disa­bling ima­ges was bet­ter in the pre­vious ver­sion. One extra click is nee­ded now.
    – disa­bling ima­ges w/o refreshing the page would be splen­did.
    – ele­ments should be out­li­ned with dif­fe­rent colors (ex. abso­lute — red; fixed — green and so on)

    Thanks for the work again :)

  34. Ian Moody says:

    Great work with this update Chris. I’m only an ama­tuer web deve­lo­per making pages more for myself than anyone else but your exten­sion is still really use­ful. Howe­ver I also have some bad news to report: The rip-off is back, with the same sto­len icons and the same copied-verbatim fea­ture descriptions.

  35. Flack:

    - The resize list is con­fi­gu­ra­ble so you can add it your­self — please read the FAQ.
    – Disa­bling ima­ges is under an extra menu, but this was done for con­sis­tency as part of the menu reor­ga­ni­za­tion.
    – Unfor­tu­na­tely disa­bling ima­ges is an inter­nal fea­ture to the brow­ser and requi­res a refresh. Any change would be a change in the brow­ser not the exten­sion.
    – I’ve added the uni­que colors for the ‘Out­li­ned Posi­tio­ned Ele­ments’ fea­ture to the to-do list.

    Ian — I had noti­ced that and will be con­tac­ting them about it again.

  36. Flack says:

    - My bad, sorry.
    – OK, roger that. But still it was more usa­ble ;)
    – Yup, I see. But may be there could be another way? Like “Make Ima­ges Invi­si­ble” with dis­pla­ying the alt-text.
    – Great!

  37. aliotsy says:

    THANKS! This is awesome!

    I ran into the same issues that Milou and Kent did. I had to res­tart Fire­fox in Safe Mode just to be able to use the brow­ser. Fixing this is sim­ple: when I read the ins­ta­lla­tion docu­men­ta­tion, I rea­li­zed I nee­ded to unins­tall the pre­vious ver­sion of the tool­bar. Howe­ver, the first time through I had no rea­son to read the docu­men­ta­tion since I hadn’t run into pro­blems yet. ;)

    Chris: Would you be so good as to men­tion on the main WDT page the fact that current users need to unins­tall first? I figure it could save some peo­ple a lot of confusion.

  38. Dustin Diaz says:

    *Dona­ted*
    Thanks bro.

  39. aliotsy — I’ll update the page with a note about this.

    Dus­tin — thanks! :)

  40. Huvet says:

    Hi there, thanks for a great extension!

    I use the View Source but­ton alot since I’m in a help chan­nel for #CSS. Pro­blem is that you have chan­ged the View Source but­ton to make me click twice to see the source, this makes is unless imo, since I can easi­liy rightc­lick anywhere and select view source there… Anyhow, you pro­blably think I’m lacy but is there some way I can manually change this in just my version?

  41. Nick Cowie says:

    Thank you for Web Deve­lo­per exten­sion, it has saved me con­si­de­ra­ble time and my sanity on a num­ber of occassions.

  42. Huvet — The but­ton has been expan­ded for the extra fea­tu­res such as ‘View Frame Source’ and vie­wing the source in an exter­nal edi­tor. There is no way to change this just for your version.

  43. Bri­lliant work as usual Chris, thank you so much for this outs­tan­ding extension.

  44. Craig says:

    Bri­lliant exte­nua­tion… I have become so depen­dent on it, I have dif­fi­culty deve­lo­ping web­si­tes without it!

    Any­way, going along what “Huvet” was saying… On the options, “View Source” page, would it be pos­si­ble to have a tick box to con­vert the “View Source” menu back into the sin­gle but­ton — those new fea­tu­res in the menu are great, but I per­so­nally pre­fer the sin­gle click.

    Also, I know I have the book­marks menu, but it would be really good if the links to the W3C docu­ments came back… having all the web dev stuff together really helped.

    Any­way, you amaze me again, I did not think it could get any bet­ter… but it looks like there is allot for me to play with today (yay).

  45. Aleksandar says:

    Awe­some job on this exten­sion, Chris.

  46. Aleksandar says:

    I can’t get it to work pro­perly. :(
    I star­ted in Safe mode, deins­ta­lled, ins­ta­lled 1.0, but simply none of the options work. Only view source, about the likes.
    Disa­ble sty­les do not work, Out­line XX ele­ments (I tried seve­ral) anything I clic­ked in Infor­ma­tion menu.

    Any ideas? I rever­ted back to 0.9.4. which works fine.

    (my pre­vious com­ment sea­med to be made too early :( , based on fixed list)

  47. Alex Burr says:

    Down­load error. Any ideas?

  48. Michael says:

    YewWWW!!!

    Thanks for this. You make me work har­der — or bet­ter — not sure but either way this exten­sion is a must have if your a web desig­ner. *5 stars* in my book.

  49. Nathan Logan says:

    A heart­felt thanks for a job well done. You made my life easier, more effi­cient, and ove­rall, happier.

    Thanks!

  50. Alek­san­dar — My only sug­ges­tion would be to try the exten­sion under a clean profile.

    Alex — Please read the ins­ta­lla­tion trou­bleshoo­ting sec­tion of the documentation.

  51. Joshua Welderson says:

    Thanks so much for this, Chris. I love the new edit HTML fea­ture, as well as… well, all the others. I think your exten­sion also con­ver­ted someone from Opera to Fire­fox today (quite unintentionally).

    You rock. Keep up the good work!

  52. Fan­tas­tic! Just when we thought that this exten­sion couldn’t get any bet­ter, you go and outdo your­self with ver­sion 1.0. All those extra fea­tu­res, with the bri­lliant Edit HTML fea­ture too. How long I’ve been loo­king for that feature!

    *Please* keep up the inc­re­di­ble work!

  53. Davide Andrea says:

    I would like to join the throngs applau­ding your work. My abso­lute favo­rite fea­ture is View Gene­ra­ted Source — indis­pen­sa­ble in trou­bleshoo­ting scripts that write to the page.

    I am about to donate, and I was going to ask you: all these peo­ple who thank you, do they also donate? How are we users doing in sup­por­ting you?

    D’de

  54. Davide — As for dona­tions sup­por­ting me…let’s just say I won’t be quit­ting my day job any time soon! :)

    Howe­ver, I have had about 15 peo­ple donate since the release and those dona­tions (along with yours) are greatly appreciated.

  55. Dustin says:

    Ben,
    Just so you know, those two are bud­dies any­way, so that post you lin­ked was all in good fun as they’re ‘ol time buddies.

    I per­so­nally know Wally as that type any­way. He’s a good friend of mine as well.

  56. Steve B says:

    WOOOOOOOOW !!!!!!!!

    The best just got bet­ter!
    Its the first exten­sion I reach for, almost always spots the flaw first, is a pain in the a## for poin­ting out the bad stuff.… but you end up with a per­fect page!

  57. Huvet says:

    Thanks for your replay Chris.
    I have to agree with Craig a check­box in the options would be a great addi­tion in the next ver­sion. I can’t belive this minor issue is anno­ying me so much but it does.

  58. Windows-Zerstoerer says:

    The exten­sion is great! Easy to use and very power­ful.
    Is it pos­si­ble to edit the HTML of a frame? I tried seve­ral ways, but I always got the source of the fra­me­set to edit.
    The tool­tip of all the menu items of the web deve­lo­per tool­bar is the last tool­tip that was dis­pla­yed in anywhere Fire­fox (except tool­tips of book­marks) — if I look at the tool­tip of “CSS” (in the tool­bar), every item has “CSS” as tool­tip, if I look at the tool­tip of the reload but­ton I get “reload page” as tooltip.

  59. Josh says:

    The Web Deve­lo­per Tool­bar is a great tool that is a must have for any web desig­ner! Keep up the great work!

  60. Ins­ta­lling 1.0 broke my Fx 1.07. Menu and address bar inac­ces­si­ble, no home­page loa­ded, you can­not do anything.

    I had to start in safe mode and deins­tall 1.0 right away.

    Could this be a sign that it’s high time I upgra­ded to Fx 1.5?

  61. Huvet — I’ll think about some sort of com­pro­mise, but this is cer­tainly not a high-priority for me. The key­board short­cut is a solu­tion in the meantime.

    Windows-Zerstoerer — Please see the known issues about ‘Edit HTML’ not wor­king with fra­mes and this forum topic about the tooltips.

    Paul — Please see the note at the top of this page and the mul­ti­ple forum posts about how to fix this.

  62. Tim Howland says:

    Awe­some job, I love the gui­des and the ruler– nice work!

  63. I love this exten­sion. I’ve just star­ted to mess with CSS/HTML about 2 months ago. This makes lear­ning so much easier! Thank you, please enjoy my very small donation.

  64. Carl Backstrom says:

    I can’t tell you how use­ful i find this exten­sion exten­sion I seriously use it about 20 times a day and have got­ten every deve­lo­per I know hoo­ked on it.

  65. Tom says:

    Ever­yone who builds web­si­tes needs this tool. Total genius.

    I have a fea­ture request: is it pos­si­ble to simu­late not having flash ins­ta­lled — “Disa­ble Flash”? It’d be mucho use­ful for tes­ting Flash detec­tion scripts.

  66. mightybs says:

    Just in case you have not heard it enough, con­gra­tu­la­tions and thank you on a job well done. Unless I’m mis­sing it somewhere I do miss the CTRL + SHIFt + U for the View Source, I keep hit­ting it and then rea­lize that it is gone! Thanks again.

  67. Chris!!
    I must say, Web Deve­lo­per is won­der­ful piece of art­work, soft­ware, wha­te­ver cate­gory it is.
    Rulers and Gui­de­li­nes are ama­zing
    Thanks

  68. geeky says:

    I’ve been using your Web Deve­lo­per exten­sion since 2004, and it is hands down the most use­ful Fire­fox exten­sion out there. I wouldn’t be able to do my job without it. Thanks for all of your hard work! :)

  69. Tom — Please see the to-do list.

    mightybs — Someone else noti­ced this and I’m not sure what hap­pe­ned to the short­cut, but I have added it back in to the patch release I am wor­king on.

  70. AG says:

    The release is simply superb, and I’ve been using this for nearly a year now. What I love about this soft­ware is that any user can grow with it over time.

    I was won­de­ring about the base href that gets thrown in to the code. Is that a neces­sity for web­de­ve­lo­per to ope­rate? The only rea­son is that I was whip­ping together some code for an Ebay lis­ting to then throw into the Ebay desc­rip­tion, but Ebay won’t accept anything with a base href in it. I obviously just edi­ted that line out and moved on, but it would be nice if it wasn’t there to begin with.

    But if it is a neces­sity, then I can cer­tainly live with it.

    Thanks again.

  71. AG — The base href is a known issue and I’m loo­king into a way to fix it.

  72. NaXo says:

    Just one thing to say: IMPRESSIVE ;)

    A really need for any web­de­ve­lo­per. Keep on the good work!!

    Gree­tings from Spain.

  73. sztosz says:

    Just another thank­full mes­sage for this

    GREATEST exten­sion

  74. derek says:

    Great tool for web deve­lo­pers, a must have!

  75. ChadL says:

    I know it’s been said many times before but it needs to be said…

    Cudos on the best and most use­ful — by far –exten­sion avai­la­ble for Firefox.

    One fea­ture request I have is to incor­po­rate a “find” tool­bar within the “Edit CSS” and “Edit HTML” side­bar. Much like the bar that shows at the bot­tom of the browser/document pane when you press CTRL/CMD+F.

    Keep up the good work man! If you need a hand with anything let me know, I would love to lend a hel­ping hand.

  76. ChadL — Search is already on the to-do list for ‘Edit CSS’ and I’ll add it for ‘Edit HTML’.

  77. Peep says:

    Same pro­blem — ver­sion 1.0 doesn’t work, nothing except View Source and Resize works, no CSS, Forms etc… Deins­ta­lling doesn’t fix the pro­blem. Reins­ta­lling back 0.9.4 works, 1.0 ver­sion not. Any ideas? I am using 49 exten­sions, it would took an hour to get it run­ning a clean install…

  78. Aleksandar says:

    Chris, just to let you know — I reins­ta­lled Fire­fox com­ple­tely (thus star­ted with clean pro­file) and ins­tall went fine. I have no idea what cau­sed the pro­blem in the ori­gi­nal install.

    WDE is defi­ni­telly worth more than these 5mins it took me to deins­tall and get all my exten­sions and theme back. Great stuff you have here. I never gave a donate so eagerly.

  79. Peep — If unins­ta­lling and re-installing does not work then my only sug­ges­tion is to try with a clean pro­file, sorry.

  80. ChadL says:

    :) I saw the list after I pos­ted. Thanks!

  81. Brian says:

    Thanks for con­ti­nuing to work on this exten­sion. I made a small dona­tion through Pay­Pal, hope­fully others will do so as well.

    Fea­ture Request: Disa­ble Flash

  82. Brian — ‘Disa­ble Flash’ is already on the to-do list and thank you for the donation.

  83. Tonya says:

    This is the most fan­tas­tic exten­sion I’ve seen added to Fire­fox! Thank you so so so much for a tool that is actually something I can’t do without. In fact, I’ve got this on com­pu­ters where the user isn’t even a Web deve­lo­per. I would surely donate if I was an adult (I’m just a geeky teen) and my parents allo­wed me to.

  84. bart says:

    ABSOLUTELY AWESOME — How about find func­tio­na­lity in CSS edit side­bar? CSS could be rea­donly and when you click on a par­ti­cu­lar rule set it would open up in its own tex­ta­rea for edi­ting. I really don’t know what the best way of imple­men­ting this is…or even if it’s possible.

  85. Margaret says:

    Just wan­ted to know if you got a little something if someone clicks on the Goo­gle tool­bar on your home page and then ins­talls it. I don’t have the tool­bar yet and will click from your page if it’s good for you. ~margaret

  86. Mar­ga­ret — Yes, I get a small refe­rral fee if you click and ins­tall from the Goo­gle button…so click away! :)

  87. Hi Chris!
    Phe­no­me­nal tools — thanks!
    I didn’t follow ins­truc­tions for upgra­ding — uninstall/install.
    On Fire­fox I just selec­ted the Web Deve­lo­per and clic­ked the Update button.

  88. Gabriel says:

    Bravo! Con­gra­tu­la­tions! You made THE tool for web development.

  89. Alan says:

    Great work. Keep on going.
