Happens to me too.

I close firefox. Kill the process from the task manager and then open firefox again

I haven't found out a good solution for it

EDIT :
It has nothing to do with Keylogging
BlaZe Reviewed by BlaZe on . 1-2-3 second delay in firefox Okay .. I do have a problem while browsing in firefox. The problem appears only while i'm using the cmputer i'm using right now. I don't face this on any other computers so there's probably something wrong with this one .. The problem is.. I am typing and everything stops up for 2-3 seconds and then it is back to normal. The same "stop" happends when I change tab. Rating: 5
