Comment 4 for bug 222243

I've had problems with bookmarks too but my firefox3 is an upgrade. You can see into the firefox's profile folder (~/.mozilla/firefox/*.default/). Ther was two bookmarks files into my profile folder:

    "bookmarks.html" and "bookmarks.postplaces.html"

Rename the first of them to "bookmarks.html.something" fix me the problem.

It's seens "bookmarks.html" is the original bookmarks file from Firefox 2 . "bookmarks.postplaces.html" plays a role in updates fron ff2 to ff3 and posibly in ff3.0b4, in ff30.b5 bookmarks are keept into sqlite format and bookmarks.postplaces.html is not update.
