Hey,

I read the crash reports, and it sounds like you have malware.

You can try these free programs to scan for malware, which work with your existing antivirus software:

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• TDSSKiller - AntiRootkit Utility
• Hitman Pro
• ESET Online Scanner

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Please try running these apps in Safe Mode. You can find instructions on how to boot into Safe Mode in Windows 8 at this site. Hope this helps!

I have installed all these tools and scanned my computer. They all found nothing but some optional PUP (like toolbar or some programs installed accidentally but which are not real virus), but I cleared everything that was detected.

I will see in the following days if it solved the problem and I would not hesitate to update the topic.

Thank for your help.

Hello sidonfack, try to delete the user.js file in your Profile folder, and check it again.

[to open the profile folder go from : Firefox button > Help menu > Troubleshooting Information > under the Application Basics section, click on Show Folder.]

(The user.js file does not exist by default, you can create the file and some programs create the file also.)

thank you

Hi sidonfack

That is a problem with the Flash plugin.

You can check for problems with current Flash plugin versions and try these:

• disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

Hi all,

Cleaning all PUP, toolbars and other ... have considerably improved the performance of my firefox, it responds very quickly now, but unfortunately it did not solve the problem because I still have a crash each 2 days. I have submitted the 2 recent crashes report.

The memory monitoring tool shows me that the firefox memory usage keeps growing even when I close firefox tabs one by one. It grows until 2800000 and then firefox becomes slow, when it reaches 3200000 the crash occur. Do you think that a particular web page may cause that? For example by adding hidden object or script (like facebook, gmail chat etc ...) in the pages, and if there is a way to prevent that?

For info, I have deleted user.js. Realplayer and hardware acceleration are disabled but nothing change.

Thank
