Mozilla/5.0 (Windows NT 6.1; rv:2.0b13pre) Gecko/20110322 Firefox/4.0b13pre Works fine for me. Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile
Flo, do you have NoScript installed? Does disabling it solves the issue?

Interresting thing: after starting Firefox in Safe Mode, the same problems occured. Then I started Firefox in Normal Mode and now everything works just fine - strange thing, I didn't deactivate any addon (only DownThemAll and the WebDeveloper addon is installed on my system). I just installed the new version on another system with the same addons, but there are no problems with the tabs. The only difference: I removed the old Firefox version before I installed the new one. Either it's an installation problem when you install the new version without removing the old verion before installing the new one or it has something to do with the profile. Anyway starting Firefox in SafeMode and restarting it in "Normal Mode" fixed the problem for me. Sorry, it seems that it isn't a bug, sholud have discussed this in a forum / newsgroup. Thanks for your help.
