If you volunteered testing firefox-3.0 preview packages you will be asked which profile you want to use in future …

The new addons management rocks and you can install ubuntu packages by selecting the right top link “Get Ubuntu Extensions” ...

Btw, firefox 3 beta 3 now has a native gtk print dialog …

The preferences dialog has a polished look as well …

... and some users will definitly be happy that the ability to add certificate exceptions is available again …

Last but not least firefox 3 is still beta and thus not perfect (yet). Read the Release Notes for more details on the glitches in this release.
Enjoy!!
