Firefox is about the only piece of software in my setup that occasionally crashes. I say "occasionally" for lack of a better word, it's not "all the time", but it is definitely more than I would want to.
If that was caused by bad memory, I would expect other software to be similarly affected and hence crash with about comparable frequency. However, it looks like I'm falling more into the other 90% of cases (unsurprisingly) because I do not observe other software crashing as much as firefox does.
Also, this whole crashing business is a fairly recent effect - I've been running firefox for forever and I cannot remember when it last was as much of an issue as it has become recently for me.
