Try updating your graphics drivers. Faulty, outdated, or corrupt drivers can cause Firefox (and other programs) to crash.

Thanks for that, but I've done that, and it didn't make any difference.

Hello,

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

• Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
• In the Firefox options window click the Advanced tab, then select "General".
• In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
• Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Did this fix your problems? Please report back to us!

Thank you.

That's terrific! Hardware acceleration disabled. About to restart Firefox. Since this is an intermittent problem, it may be a few days before I know if it works. Thanks very much, have a great weekend, and I'll report back.

Well, ... fingers crossed and all, ... but the last few times the graphics accelerator crashed it did not take Firefox with it! Yay! So thanks again, and I'll be back if posting this jinxes it. :^)

I have similar problem. Win7 x64. I tried x64 Firefox (nightly build version) as well as portable PaleMoon x64 (based on v.24 of firefox). In both cases I get "display driver stopped working and recovered" at least once a hour. I have the latest AMD/ATI driver, I switched off hardware accelleration, I also increased TRDdelay in registry to 8sec - nothing helped. I even bought a new video card that had more videoRam - still have a problem. Eventually, after 3-4 crashes of firefox/palemoon my whole system blue-screens. However, I am runnign waterfox x64 portable (based on Firefox v26) and it works just fine. No problems of any sorts, no error messages in a couple of weeks. And the hardware accelleration is turned on. So, obviosuly this does not conclusively prove that something is wrong with Firefox or paleMoon, but for some reason Waterfox solves this issue for me. [I understand that I cannot draw any conclusions on a sample size of 1 :-)]. I hope someone in firefox dev community can figure this out.

Thank you.

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

Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

HI -- Thank you for your advice, but as it turns out all I had to do was to change to screensaver from the default to a simpler one.

Screensaver? That is an easy change. In my case I did not see any obvious correlation since screensaver seemingly was not involved when the problems happened. But stranger things have happened, so I will try this.

Also, I use a couple of programs suggested by co-rel, but will try to run them all (this is a bit more time consuming than chaging screensaver).

Running is safe mod also a bit harder since it runs in low res mode, but I will try that too. I also found out that lowering color from 32 bit to 16 bit makes the problem a touch better - the message/crashes still occur but not nearly as often.

Thanks everyone for your help/suggestions.
