I am using ff 6.0.2 with Fedora 12, and have a problem of the browser hanging sometimes. I have started firefox in safe mode, but it still happens. It usually happens when I am trying to open a bookmark inside a folder inside the Bookmarks toolbar. When I click on such a folder on the toolbar, firefox starts to hang, which can be more than a minute! Animations from commercials etc. continue to work though. As I have not yet selected the actual bookmark, It is not a problem of downloading the webpage itself. It happens maybe every 1-2 hours or so. Also, I did not experience such a long hanging time ever with a previous version of firefox. I would appreciate any help in this matters. Alex
