Uninstall and Reinstall again.

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Hi guys,

Thanks for responses.

I haven't tried a reinstall yet. Would all my bookmarks and addons remain?

Just tried in Safe Mode (all addons disabled, and hardware acceleration disabled) and the problem still remains.

could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might give us a clue what is going on...

I just rebooted Windows, opened FF again, and now the tabs are working properly!!

Good old reboot!
