Am working on some WordPress development projects, using FF with Firebug a lot, refreshing pages, deleting history, etc. I've noticed that after heavy use that way FF 3.3.> started crashing. Sometimes it also crashes after the computer has been idle for a while and I continue a session in the open browser.

I read about checking for crash signatures, but nothing has been recorded for August and that's when it happened more frequently. Have updated to 3.5.11. No joy. I need to be able to use Firebug, so don't want to update and render the Firebug version incompatible.

I am using BitDefender daily. Using Window 7 Pro 64-bit on a Intel, Core 2 Quad CPU. Any thoughts?

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 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 this article for information about troubleshooting extensions and themes and 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.
