I had a problem with Firefox. When I start the firefox, it works. But for a while (randomly) I can't click on firefox menu anymore. The right click menu doesn't work either. The dropbox (select box) in website does not work.
I'm using Xubuntu 12.04 64 bits:
Linux minh-desktop 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux.
Everytime I get this problem, I have to restart the firefox. I had no problem with Firefox 12 had the problem with 13 and 14. I'm not sure if Firefox version or Linux Kernel causes the problem.
I tried safe mode but it doesn't help.
Please help. Thank you.
Solved! Go to Solution.
You can consider the Reset Firefox feature via Help (Alt + H) > Troubleshooting Information. To revert to the previous profile, you can close the new profile, start Firefox and choose the *.default profile. While the Profile Manager is open, you can also delete the newly reset profile (the one containing random numbers).
The Xubuntu forum would also be helpful.
If you have Flash media open it could freeze the mouse for a few seconds. Also, you can check if there are any default Extensions and Plugins in Tools (Alt + T) > Add-ons and try to Disable those.
It doesn't just freeze the mouse for a few second. I can still use mouse and left click but all menus are hidden. I think when it happen, only 1 layer of web/browser can display.
I try to disable all plugins, let's see what if can help. Thank you.
You can try to create a new user account and check Firefox in that. You can also try the failsafe mode in the login screen options. The Xubuntu forum may also have useful pointers on new issues.
I got the same problem here: menus + context menus freeze on my friefox 14 . All the usual tips didn't help (new profile, new .mozilla, safe mode, removed any unity dependent stuff). I got these problems when I went from ubuntu 10.11 to 04.12. I have the same problem with thunderbird (can you confirm this?) but not with drop down select boxes in web pages. Chrome is working fine. No clue yet. Will keep you updated.
and some other entries are refering to a problem with pulseaudio + firefox / thunderbird.
I removed ~/.pulse +!!! ~/.pulse-cookie . Removing ~/.pulse-cookie solved my problem. If you you are experienced you could try: "strace firefox 2> /tmp/strace.txt". open a menu and kill firefox once it freezes. Open /tmp/strace.txt and have a look at the last lines. If you see sth. like ".pulse-cookie" you're on the right track. Some people completely removed pulseaudio from their system. In my case "rm ~/.pulse-cookie" helped.
I confirm that I have the same problem with the thunderbird but it's not quite often like with the firefox. I tried strace command but I didn't find any "pulse". But I removed the ".pulse-cookie" directory, hopefully this will help. I will update the result later.
