I have never used Safari on my Mac yet it has frequently just stepped in, uses it's theme and no other, hx, bkmks, contacts, all gone! Is this due to Ff crashing?

Question

I upgraded from Tiger to Snow Leopard in my last desperate attempt to find all my Ff stuff. (OS x v 10.6.4) I subscribed to an expert opinion site to get their help (just sort of tightened it back up, reinst. Ff 3.6.8. I've been online for hours, tried to purchase a game from Gamehouse, backtracked to get an email address, tried to return to order,; Gh never heard of the game that was in my cart, and boom, hey, what's this theme? Safari! It's Ff, sort of, but shows no ext's or addons and won't even show themes. The last year or so Ff has crashed often and even more often will not quit and must be "forced quit." Often I can't tell what's hung up til it's too late. Fixed 3 days ago, messed up again. Granted, I was all over the place uninstalling old apps etc and trying to corner Safari or delete it, but I don't pile up a million windows. I've been emptying trash "secure" style and it takes hours; that had just finished. But when I tried to find a contact to add to the game and resume the order, OH! and at the end of the 60" free trial...the screen was shattered like a windows blue screen moment.

Well, if your Firefox is crashing, it's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.
If you "don't know where Firefox is" or "don't know how to start Firefox", see [http://support.mozilla.com/en-US/kb/Installing+Firefox this article] about installing Firefox. Your profile should be safely stored. Reinstalling and even uninstalling won't delete your data (unless you tell the uninstaller to do so), so don't be afraid of installing Firefox again, preferably in the default location.
