User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0 Build ID: 20120420145725 Steps to reproduce: When notified of a new version I upgraded to it and my world ended as I knew i. Actual results: It crashes constantly and I have to keep up restarting it. No messages given as to why, just gone and the window closed. Expected results: I've used firefox for many years and never had this kind of problem. Now I can't get past it.
Can you provide the crash ID (bp-...) from about:crashes? Does it happen in Safe Mode (see https://support.mozilla.org/kb/Safe%20Mode)?
please reopen if fails with current version in safe mode https://support.mozilla.com/en-US/kb/safe-mode for now, there is not enough information
