Firefox uses all of my cpu
Hello, I'm using Windows 7 and the latest version of Firefox. Since a cople of days, Firefox use 100 % of my CPU. It becoms very, very slow, even doesn't work anymore. I have tried every solution on mozilla support to this problem, but without succes. I even tried other things I found on the internet. It is a problem more people are confronted with. Greetings, Geert Tilmans

Please do this as I see you have a couple : Mozilla experiment, called 'Shield Studies'. Without even knowing it, you may have volunteered for this Mozilla experiment. Would you go to : Options => Privacy & Security => under 'Data Collection and Use' : Did you uncheck : 'Allow Firefox to install and run studies ' or is it checked ?
To check if you are enrolled in these studies :
Type in the address bar about:studies
Any extensions that you see listed there, you can either disable or remove, just like this Safe Browsing version 4 (at the end of the experiment they will be disabled anyway). See for further information : https://support.mozilla.org/en-US/kb/shield
Please leave send info to Mozilla ticked or I would not have know this.
You can try to modify multi-process settings to see if this has effect. You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
