Why is firefox so painfully slow?

On every PC I have Firefox is painfully slow in comparison with the other browsers. When will the developers wake up, stop blaming add-ons and other client-side issues and take note that Firefox is just simply...slow almost unusable.

I do find it reliable in terms of loading things off the server consistently (unlike the broken mess that is Google Chrome which has a mind of it's own), however its slowness is really frustrating and it's even more frustrating to see that the blame is put on add ons, Windows and anything else.

THE PROBLEM IS FIREFOX, Please work on fixing the performance issues.

You can check if it helps to start Firefox in Safe Mode by holding down the Shift/Options key.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.


Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.


Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.
