Mostly works, but not quite Rated 3 out of 5 stars
Googlebar covers much of the features of the old Google Toolbar, but not quite. Some bugs/missing features (when run on Firefox 12) are:
- The search navigation buttons don't work.
- Popup menus from the toolbar have no background
- No Google Bookmarks button. The GMarks add-in is good enough, but not as nice as Google's toolbar button
- No sharing button. The Shareaholic add-in is an adequate replacement
- The GMail button asks for login information whenever you click. If I click cancel, GMail comes up OK, because the login cookie is present in the browser. It really shouldn't have to ask.
I hope the author decides to update this useful toolbar, fixing the bugs and implementing missing features.
