As of a week or so ago, when Firefox starts, it crashes. Same goes with Totem (Movie Player) and Amarok (Actually, Totem hasn't worked for ages). With Firefox and Totem, running in terminal gives a 'Segmentation Fault'. With Amarok, I get a signal 11 (SIGSEGV) fault which I understand is the same (maybe!).
When I run Firefox as root ("sudo firefox") then it works. Same with Totem. But that's quite annoying on all sorts of levels! I've tried completely removing firefox, deleting .mozilla from home directory, then reinstalling. Same problem.
When I launch Amarok, that crashes immediately with a signal 11 (SIGSEGV) fault. When I run as root (via terminal) it does start, with various error messages on display.
This is all quite recent, maybe a week or so ago. I have all the updates (levels 1-3) from mintUpdate, and I recently marked all upgrades in Synaptic to give that a try (it upgraded the kernel) but again this hasn't solved anything.
This is serious - some help would be appreciated! It is possible some files somewhere have the wrong permissions?
EDIT: Anyone? At the very least, it would be helpful to know whether this stands a realistic likelihood of being fixed, or whether a fresh install might work best!

P.S. This is a repeat of viewtopic.php?f=47&t=30886 but with a Subject name that is a) more accurate, and b) hopefully more likely to get some advice!
