I like using Firefox, because of all the add-ons it has. The one I like best is the CSS editors that you can add to it. It makes it so much easier customizing my store templates.
Firefox is my favorite browser for several reasons as it is more secure and has many features which other browsers lacks but I found it a bit slower than opera .
I think firefox is the best browser. But I do keep IE around...because every once in a while there is sites that IE will load that FF won't. And for some reason, I have trouble priniting my mail (for receipts, for taxes) in Firefox, so also use IE for printing e-mail.
I'm actually using firefox 2.0 for my development&(if all else fails) browser, 3.0 is a lil bloated for me. Google Chrome is my main browser of choice. I try to do everything in Chrome, but when it fails, (like the stupid checkbox bug) I'll switch to firefox.
I guess, it has the most plugins and it's very stable. Google Chrome however is faster, but Chrome has some annoying bugs that keep me from using it all the time.
i love firefox, i have been using it for 3 years! I love all the addons that it has, as well as the themes. everywhere i go, i encourage everyone to use firefox. my favorite plugins are: web developer, colorzilla, and more, but too much to name here.
I like firefox browser because it's download is something else. It makes download very fast. Nice one from Google. Thumbs-up!
I've never had a problem with firefox, IMHO all web pages look better in firefox. There are so many quirks in IE, I hate that i have to program css specifically for them.
