About 500 bookmarks are suddenly lost, and it looks like IE.
Also I really dislike what they’ve done with the grey area around the favicons. My first impression is it’s pretty much terrible.
Default theme looks nothing like IE. In fact I think its missing some usability buttons but the toolbars are easily customizable and you can install addons and themes to change things. Took my 10 addons to make it look and have some of the features of IE including inherit the glass elements of the Vista Aero theme. If only there was an easy way to put buttons on the tab bar in Firefox now, I could eliminate some of the screen real estate it uses.
