Now after a month you are feeling that your firefox browser is working sluggishly and you are getting irritated with it and you don’t want to reinstall as if you do so all your extensions will get deleted then what to do i am going to explain it to you.
First of all make sure that all firefox windows are closed
Go to
start > run And type
firefox.exe –profilemanager
See the image below
Now a window will pop up with the look below
Click on
create profile > next > enter the name of profile > finish
[link removed]
Thanks
