I'm a little confused... Blue screen sounds like Windows, but when you posted, you passed through the Firefox for Android section. Which is the system with the problem, and what OS version?

Also, when you say you downloaded something, if you think it might be related, can you check your history and see what it was?

I'm currently using my android phone right now and yes, it does seem awkward using it. I think I might of posted this at the wrong section... BTW, my computer is a windows xp 32 bit; I downloaded this game file and I think the file might be causing the problem.

Can you get Firefox started on your XP system long enough to review your add-ons? If necessary, you can start Firefox in "Safe Mode" by holding shift key when you double-click the program icon. Then you can check for unrecognized add-ons:

orange Firefox button (or Tools menu) > Add-ons

The Extensions category usually is the most relevant, but Plugins and Themes also could present problems.

If you can track down what game or game add-on it is, running it through a web search may reveal whether it is a known source of problems.

A BSOD means a Windows problem with a system driver or system services.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.

You can open the Windows Event Viewer to see details about the BSOD crash.

Try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You can use one of these to start Firefox in Safe Mode:

• On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
• On Mac, hold down the Options key while starting Firefox
• Help > Restart with Add-ons Disabled
