Firefox crashes with plugin stop working and Some unknow addons get added to my browser

Posted

I am using Fire Fox latest version and my browser crashes sporadically with plugin container stopped working and some unknown addons gets added to my system. I usually just remove them, but is happening more frequently now. The last unknown addons were "RespEactSeale" and "Steam Trade Helper". Some times it also removes my Adblock plus addon from the browser.

You may have ad / mal-ware. Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.


check this:

  • see if there are updates for your graphics drive drivers

See:


You can check for recently installed suspicious or unknown extensions.


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.

You can also do a check for a rootkit infection with TDSSKiller.
