We know there are a lot of others besides those on this list, so feel free post any favorites and we will make sure they are added (if they’re worthy of course).

Here’s a list of our favorite Firefox add-ons. Firefox is an amazing browser by itself, but these extensions bring the application to a whole new level. I can’t even imagine what life would be like (especially debugging) without half of these extensions in our arsenal. Whether it’s to save time with shortcuts, or to help get through those little bugs that get you completely stumped, these extensions are great tools for every web designer.

Now lets just clarify (before we get too many insulting comments) that we understand some of these extensions can replace multiple other one’s that are listed. For instance, as of right now the only “activated” plugins we have in firefox are the Web Developer tool (an absolute must) and Firebug (another absolute must). Some developers prefer individual plugins rather then getting bundled apps that have features they are never going to use. We have found each one of these extensions to be useful and that is why we have listed out ALL of the ones we’ve found helpful.
