Firefox 2.0 has been released and has more than 2 million downloads in 24 hours. Including mine.
The main updates seem to be in more RSS functionality, a tastefully updated UI (including better tabbed browsing), and the ability to restore work sessions. The latter feature is one I will appreciate – when you work researching something and your computer freezes, being able to bring up all the tabs again is reassuring. (Haven’t tested this yet, luckily, but I am sure I will in the not-to-distant future.)
Firefox can sometimes be a memory hog – hopefulle this has been fixed in the new version.
Seamless install and transition from earlier version, as usual with Mozilla applications. Highly recommended.
Update: Slashdotters (some, at least) think 2.0 inferior to 1.5. So far, I disagree.
