Have you disabled Hardware Acceleration? Did you surf the web in safe mode?

Hi Fred, I have tried save mode, that made no difference. I turned hardware accelarator of just know. We'll wait and see...Thanks so far. Kind regards, Ype

Hello, Unfortunately turning off 'hardware accelarator' did not solve the problem, although it looks like that mozilla crashes less often. (not every 10 minutes anymore). Any other tips? Kind regards, Ype

Try to create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Do a malware check with several 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.

Hello, I did not download and execute all the programs you suggested. I have DrWeb as antivirus and i am pretty content with them. Their scan has noticed no problems, furthermore I have no indication whatsoever that I have a virus, malware etc installed. The programs you suggest will slow down my pc and I think that the problem lies with Mozilla. So I hope you can find some other solution. Kind regards, Ype

Some add / mal-ware hides from virus scans. Please use the above programs.

Hello I have downloaded and executed the programms suggested above, and beside some cookies nothing was found. I have also reset my mozilla profile (have not removed yet). So far nothing helps. Personally i think that there must be some conflicting software, or my virusprotection causes the crashes. But I have no idea how to detect what is the problem. Chrome crashes to every now and then.

One of the crash reports flagged;

d2d1.dll = Windows

Perform a System File Check to fix corrupted system files http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

See if there are updates for your graphics drive drivers https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

I've called the big guys to help you. Good luck.

i have done al of the above, but nothing helped. However I have got another virus protection right now. I have changed from DrWeb to bitdefender. All problems are solved now. I think that DrWeb was the reason for the crashes, it blocked to many scripts running on internet pages. Maybe this is useful information for other users

That was very good work. Contact the support for DrWeb and tell them.
