So far I’ve tried disabling the DOM Inspector and Talkback in Firefox and also Windows XP’s Webclient service (which has been cited among others as a possible culprit of the XPCOM Event Receiver problem) – none of this has helped.
For me the problem seems to be a tad more serious than for others reporting this, since just by running Firefox for a while the system eventually loses all networking capabilities and refuses to open the Task Manager (I’ll try grabbing a screenshot, of the alert box notifying about the failure, if I can the next time it appears, although it is in Finnish), at which point the only working solution is to reboot – which, of course, is when I’m greeted with the XPCOM not terminating properly
nag.
The strange thing is, if I open up the Task Manager and leave it lurking on the side while FF hoses the system, from there it looks like there’s nothing alarming going on – no single process is eating up all the resources. The only abnormality is the firefox.exe process not terminating when I close the application window.
Right now I’m running Firefox in Safe-mode and with anti-phishing disabled in addition to all the stuff mentioned above. I’m hoping I’ll come across something that works, because otherwise I’ll have to switch to Opera or something, and I’d really, really hate to do that.
