Reproducible: Sometimes Steps to Reproduce: 1. 2. 3. Unfortunately, about:crashes does not have any information, so I'm unable to provide any kind of traces. This behavior never occured with Firefox 2.x, as I had uptimes of weeks. Since starting with Firefox 3.x, I inevitably get a lock up in Firefox in under a week of using it. The above listed triggers (clicking on a link in gmail, and clicking 'never for this site' after http authentication) are merely the last few that I can recall. Now that I have a bug filed I will be more diligent about remembering exactly what it was that caused the lockup.
Firefox can not freeze the whole OS (unless you use windows 95,98,ME) because it doesn't contain a kernel mode driver. It can make the system very slow if Firefox allocates all the memory but the taskmanager should come up after some time (minutes). If you really get a hard freeze (mouse pointer doesn't move) then it's a clear system or driver bug and it doesn't matter if you get this only with Firefox and only with one Firefox version, it's stilll a system bug. -> invalid
Just had another freeze with firefox 3 after clicking on a link in a webpage. Is there any kind of dump or crash log I can enable in firefox that will allow to me have some idea of what the problem might be?
And, (forgot to specify) that I went back to the link right after I restarted and it worked fine.
