Firefox has been crashing periodically - the latest crash signature was nsXPConnect::ReleaseJSContext(JSContext*, int). How can I fix this?

Recently I was having trouble opening Firefox at all, so I created a new profile and transferred a number of my settings from the old profile to the new one. Now Firefox opens on the new profile, but it has been periodically crashing, usually after only a few minutes every time. The latest crash gave me this crash signature: nsXPConnect::ReleaseJSContext(JSContext*, int)

Hello Deepa.

You may be 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 coming from 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 and select Disable all add-ons. 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 theme. You can troubleshoot plugins the same way.

If you want support for one of your add-ons, you'll need to contact its author.
