Firefox has become very slow. It takes too much time to load any page. Google mail page almost impossible to load. Not talking about flash based pages/games ; they never loaded in teh last couple of weeks.
I was trying for days to fix the problem. The only working solution seems to be a reset of your Firefox profile. See here how to do it.
You have to know that doing this you will lose all your Firefox settings and personal information:
- Cookies
- Installed Extensions
- Bookmarks
- Browse History
But at least when reset profile is done the old profile data are saved in a folder named “Old Firefox Data”, you can later still import some things from there.
It will work for a while, anyhow in the end most likely you will need to reinstall the operating system or to buy a faster/newer CPU. Usually those problems are generated by weak CPU/hardware.
