  2. 2 Chamara

    yeps Firebug is a very useful add-on, it’s in my list too, Thanks Lakshan

    I use downLoadThemAll, Firebug and Web Developer religiously. I’m still getting used to the new del.ico.us extension.

    I don’t use Tab Mix Plus since 2.x since Firefox has most of that in built now.

    You might want to add MeasureIt and ColorZilla they are pretty useful when trying to nail down a pixel perfect design or steal pretty colors from other websites :)
    I’ll check out the rest, good list.

    What the? No Ad block ? No Mr Tech Local Install? No Auto Copy, customize google or Paste and Go 2 ? In every “top 10 firefox extensions” listing I’ve seen around the web (and there are virtually thousands of them) , these extensions were generally in the top 10 :( Besides, you’ve mostly enlisted extensions that are useful to the web-developers only, what about the general users? Not everyone wants to view page source and inspect the DOM elements once they visit a site :)

    Anyhow, those extensions you listed are some of the best out there. But I’m sorry to say that I’ve seen better :D Keep up the good work.

    Cheers :)
