User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0 Build ID: 20141113143407 Steps to reproduce: Occurs randomly, sometimes after few hours sometimes after 2 minutes Actual results: Firefox stops refreshing the main window. I can see the title changing on the taskbar when I click on tabs, but the whole main window looks frozen. Restarting firefox is the only solution. Expected results: I guess it shouldn't behave like this.

Milan, do you know who might be able to help figure out what's going on here? Csaba, can you post the "Graphics" section of about:support on the Firefox profile where you see this? Also, can you still reproduce this on the current release version (34) and/or on Nightly ( https://nightly.mozilla.org/ ) ?

Hi Gijs, I was able to reproduce this behavior with version 34. Happened after ~30 minutes while I was typing a url in the address bar.
