Firefox closes unexpectedly during a download

If I leave my pc on overnight while I"m downloading a large file ( tutorials..under 1gb) when I wake up FF is closed. I've tried 3 nights running with the same result. It's extremely frustrating.

I also can't log in to Mozilla bugs otherwise I'd report the problem but even after resetting my p/w and reloading my browser before entering the new p/w I still get the message that the username or password doesn't exist so there's no way I can log in. I'm only able to write this message because it doesn't require a log in.

Troubleshooting information

Left PC on overnight to download an 375mb tutorial. FF closed in morning and reopening FF shows "restore session". This problem is repeatable....tried 3 nights running.

Hello Jackie.

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.
