I totally agree! Firefox is the most unstable browser available, I like it and use it but it does crash a lot, in Linux and Windows.. Cant blame it on windows!
My Firefox doesn't crash.....very, very rarely!
I rarely have crashes with Firefox...even with 20+tabs open. I can't remember the last time it caused me any trouble. Meanwhile, I can't even get IE to open a link in a new window without locking it up.
I have no idea what Firefox you run or what you're running it on, but mine has been a phenomenal improvement over IE in speed and reliability, on every platform I've used it on (XP, 2000, and ME--yes, even ME!). I won't ever go back to IE as my primary browser, and now, I only use IE when I am forced to by websites that are too dumb to consider that 10% of the market and adapt their sites to it.
I am curious about your crashing situation, seriously. Is there something program wise or hardware wise you've been running on that would make your system more volatile, at least in regards to Firefox?
