    Now if only Firebug worked on FF3

    As a note, IE Tab will not work in OSX. You will still need parallels or bootcamp to test in IE (ugh…).

    Also I’m shocked firebug isn’t on the list. https://addons.mozilla.org/en-US/firefox/addon/1843 This would be my number one. There’s nothing more valuable when looking for a specific CSS bug in your site, or getting a quick idea of how a site you didn’t design (but still have to change) is set up. You can also proof changes live and in-browser.

    Another useful object, although not a firefox add-on, for those with OSX is PhotoDrop. http://www.dropping.at/ it will allow you to make quick screenshots (with measurements) and copy them right to the clipboard.

    How can a 10 best list NOT have Firebug on it? It provides targeted inspection of particular elements on any page, live alterations of css / xhtml, a better console / debug for javascript and basic bandwidth profiling. At a minimum it could replace measureIt on your list, but it is so much more. I am always finding new features it has.

  • MediaMisfit

    Great post! I didn’t even know these where available. I love FireFox!

  • Brandon

    Thanks for this list! IE Tab looks great but not available for Mac OSX! Crap….

  • http://www.metalsoftware.com/ IDX

    Yes, FireBug is definitely a must-have also, although I guess that crosses into web-developer more than just web designer. Great list.

  • http://www.howtoforward Michael

    Thanks for the list.

    Like others, I already have initiated the use of many of these add-ons.

    And like a few others, was as disappointed to find out about a couple that aren’t available for mac-prime-time.

    However, there was one, that although not available for the mac, has an equal that IS available for the mac.


    If you’re on a mac, and want the benefits of FireShot, give a look at ScreenGrab. This nifty add on will allow for both ‘what is visible’, ‘complete page/frame’, and last but certainly not least, a user-selectable option. In conjunction with all three options above, it can do so either as a save-to, or copy-to-clipboard manner.

    Hope this helps some of my mac siblings on this blog. ;)


    P.S. Fellow mac-ians, if you’ve not seen it, you must also check-out this new beta-ware: Skitch It’s not a firefox add-on, but a very sweet screen capture utility.

    Great list, got a couple that I’ll need to make room for now, thanks! The Me.dium Crowd Surfer, a social browsing add-on, is also a great tool for developers. With Me.dium you can check out who is on your site and chat with them in real-time. An easy way to get instant feedback or gauge your sites popularity. We also recently announced compatibility for FF3 as well. We’d love for you to check it out and give us your thoughts.

    great selections gino. here i am running normally with three machines all with firefox browsers and still I forget to go there first when looking for tools. the palette making tool is great.

  • http://www.smashingapps.com Sarah

    List is amazing. You did a great job to make this great list. Thanks for sharing.

    I must agree with those missing firebug. Possibly THE most important plugin for ‘fox.

    @IDX: Firebug is unbelievably handy when testing and fine-tuning layouts, so I wouldn’t really categorize it as a “web developer tool”.. more like “something for everyone”, which is not a proper reason to skip it ;-)

    On the other hand, Window Resizer, GridFox and MeasureIt seem kind of unnecessary, since Web Developer already has tools for resizing windows (and adding custom sizes), displaying custom grids and measuring things.

    Had some of these already but some nice new ones to use there.

  • http://www.katize.com kat

    Nice! Will have to try some of these out.

  • http://www.r1designs.net mdrisser

    I agree 100%, Firebug is definately the #1 plugin. Drop Measure It!, Web Developer has a ruler, and put Firebug in there.

    thanks for the news

    Great Post Gino,

    I use most of them and some more, although you can skip MeasureIt, GridFox and Windows Resizer since these functions are already included in Web Developer. Just click on your Web Developer Toolbar on ‘Miscellaneous’ and select ‘Display Line Guides’ or ‘Display Ruler’ and you have the functionality of MeasureIt and GridFox.

    If you select in your Web Developer Toolbar ‘Resize’ you can easily resize the window and also add different dimensions if you want.

    Web Developer is a great tool with lot’s of hidden functionalities.

    I’ve previously tried only a couple of add-ons. Thanks for this article. I’m interested in trying a couple of your suggestions.

    I’m a huge fan of Firebug and the Web Dev Tool bar. Great stuff for troubleshooting and refinement.
