I upgraded today and am satisfied with this new version.

So far no issues and I like how the drop down menu in the address bar is more detailed now.

Go HERE to upgrade or for a fresh install of Firefox 3.

Also, the IE 8 beta has been out for sometime as well I might give that a try soon..

I downloaded it yesterday, and I am quite pleased. I like the drop down menu in the url bar as well, and the easy access bookmark star icon in the address box. Very nice.
And of course, the skin look much better than the old one as always.

Definitely improved, but the thing that's lacking:

Supportment for older add-ons.

the best thing about the new firefox is when u type about:robots in the address bar :) makes me giggle :) i do miss some of the firefox 2 addons though that havent been upgraded to support firefox 3 yet :(

i still use seamonkey... i might have to try regular firefox again.

I had firefox with my mac back in the day...I didnt like it then, i dont like safari either...I prefer Seamonkey like my man Side_scroll'R above ^^ lol this makes me think of this vid...

Pffft, Seamonkey. Not my kind of browser.

As for the addons for Firefox, I had one skin and tamper data, but I don't ever use them so I don't even bother updating with them.

Am I the only one that still uses IE primarily? ;)

I use FireFox on occasions though mainly for cross-browser compatibility testing - and for sites that don't work properly in IE, of course!

Are there any significant changes in the new version and is there anything to be aware of apart from the lack of support for older add-ons?
