1144050 - [OS X] Firefox unresponsive after a few minutes

Status: RESOLVED DUPLICATE of bug 1142957

(Firefox :: General, defect)

Description

[Francesco Lodolo [:flod]]

I'm still trying to find a clear way to reproduce this issue, but it's already happened 4/5 times in the last days.

My iMac is set to shut down the screen after 15 minutes, but not to shut down the entire machine. When I come back to the mac, I login to unlock it and find Firefox completely stuck: the main menu seems to work (I can open the about window for example), but I can't do much else. I can't switch tabs, links opening from external applications don't open, etc.

The only thing I can do to fix it is to restart completely Firefox.

It's not related to the monitor switching off in itself (tried setting it to 1 minute). It started in the last 5-6 days, I also updated OS X to 10.10.2 in the same period, but I have the feeling that the issue wasn't there at the beginning.

It's even weirder than I thought: left the computer unattended for 15 minutes, unlocked the screen and the browser is stuck.

If I click on one of the open tabs, it doesn't gain focus. But when I switch focus on a different application, Firefox displays the tab I clicked. It's not a time issue, I need to click on a different app.

I can't write either (had to restart Firefox to write this comment). I did start Firefox from terminal, but I don't see anything useful.
