Mozilla Firefox is a fast, full-featured Web browser.

2.0 is a notable improvement over the previous versions, as far as speed and functionality. As far as Windows boxes are concerned, 2.0 (unoptimized) is faster in my experience than IE7, and usually better than IE6. On my Mac, it's bordering on Safari's speed to the point that I am almost ready to drop Safari entirely (I still use it out of habit, the previous versions of FF were noticeably slower).

All in all, a truly great browser. I've tried Omniweb, Opera, and several other browsers, and I keep coming back to Firefox because it's just plain better.

Yes 'diggn_it' I do indeed find these tools very useful.

I can see you have had a quick whip round to bash the other browsers. And yes I'm a fan of OmniWeb. I tend to use every browser I can find. Firefox does indeed have great versatility. I've had a look at and do use some extensions and will launch Firefox to use them. It's just a shame that the user experience is just not as nice. You are left to either leave all the toobars out or go to some length turning lots of nonstandard bit on and off to keep your surfing clutter free.

I work as a designer and also have problems with Mozilla browsers picking up Postscript fonts over the system fonts and then rendering them badly. I also have problems with forms and the search field being locked up on my older mac.

But as I have pointed out before Firefox is a great browsers. Perfect for those who wish to treat their browser like a Swiss army knife for the internet. What other browsers offer may at first appear to be a bit 'touchy feely' is actually tighter integration with a mac users work habits.

Everyone should keep a copy of Firefox in their applications folder, but it's worth having a long think about what one wants from a browsers and shopping around. Most have a little something the others don't.

Name one feature? How about thumbnails of all your tabs (Omniweb & Shiira). How about site specific preferences? And they need to sort those dog-ugly widegets out!! I only open Firefox to make use of those very useful web developer orientated extensions. It just not 'mac' enough. I would say I use it as about as often as Opera (ie not much). They are the same but different. Get used to how either work and they do the job, but they are not for me.

That said, if someone asks me to recommend a browser I would still say Firefox, but only because it is popular enough to run into less problem websites and certainly better than Safari.

I still get locked out of form fields on the old blue & white G3.

Google for Adblock, Filterset.G, and FlashBlock. Those three extensions should make your browsing experience a little more pleasant.

GREAT shout there. I just did as you recco'md and switched to the Deer Park release. MUCH faster especially if you have more than 4 extensions installed.
The only thing I changed was the icon from the G4 globe back to the standard firefox one.
Here is the link for those who are interested:

PS as it is the same app only streamlined, it keeps the same file structure so your bookmarks/settings/prefs etc remain unchanged. Simply trash your old Firefox (NOT with Appzapper, just the alone, leave the ancillary files) and start using the deerparks version instead.

Firefox themes especially made for Mac OS X

"The themes are based on the Mac Firefox default theme and are designed to fit well in the Mac OS X environment."

As others have said, the extensions are what make Firefox the killer app of Mac web browsers. Having become reliant on certain conveniences that I get from the Firefox extension community, it's hard to switch away even to prettier and faster browsers!

That said, the speed issue is hugely reduced (I wouldn't say eliminated) by getting an optimized build. Because Firefox is cross-platform, the official download is basically a generic executable that plays nicely with the major operating systems. In keeping with the spirit of open source, dedicated geeks from around the world have taken the code and compiled it with special flags to optimize it for particular platforms. Personally, I like the Deer Park releases from BeatnikPad for my Macbook; it still isn't quite as fast as Safari, but it's noticeably better than the default Firefox.

Very good.....but not as good as Safari

I don't like Firefox for 2 reasons
1. It's not a Cocoa application
2. I don't like extensions, Firefox looks like a Christmas tree to me

OmniWeb 5.5 b1 is much faster. But Firefox is my favorite browser on Windoze.
