User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:22.0) Gecko/20100101 Firefox/22.0 (Beta/Release) Build ID: 20130618035212 Steps to reproduce: This bug don't "show" with specific action, I can refresh, click images, link, scroll site or whatever - it's not connected with any action. Actual results: Firefox window turns out to fullscreen version continously for a few seconds (more than 10 per second), then, sometimes even shortcut (F11) don't work properly and I have to restore it manualy. Expected results: I think that browser shouldn't live with it's own life. This situation stops any work I'm doing and anyone in the Internet can't help me to solve it.
I've tried to reinstall, run without add-ons, creating new profile, but none of these has solved this problem.
Can you still reproduce this issue? have you tried verifying if it is due to some malware on your computer? https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware
It's not malware (Comodo Internet Security, DR. Web, Trustport 2013 Total Protection, Malwarebytes Anti Malware, OTL logs - found nothing). What do you mean with reproducing it? To show, what is happening? If yes, it's not that easy, because it happens suddenly.
