Firefox crashes for no reason when there is a tab open for MSN.
I use MSN as the first tab on my browser. I can open the browser and work on multiple tabs. But when I leave the browser open for several hours, it's started to crash. I've checked each of my tabs and the only time it crashes is when there is a tab for MSN open. In fact, I closed all the tabs except MSN and the browser crashed.
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).
(If you're using an added theme, switch to the Default theme.)
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the Restart with Add-ons Disabled... menu item:
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
Once you get the pop-up, just select "'Start in Safe Mode"
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Does Safe Mode or disabling hardware acceleration have any effect?
It looks like it does. The browser hasn't crashed in a few days. How do I go about finding out which plug-in or add-on is causing the problem?
Does it work in normal mode with all extensions disabled or do you need to disable hardware acceleration?
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Quit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
