Ok, well let's try this. Sometimes extensions can cause this sort of issue, so if you start Firefox in Safe Mode, can you tell me if it is still as slow as it was before?

If it is faster, start Firefox back up, then click the Firefox button in the upper left hand corner, then click Add-ons. From there, go into Extensions. Then, disable every extension you have one by one. Each one you disable, close and restart Firefox. when you notice a dramatic difference in speed, you know you found the troublemaker.

Make sure that you give Firefox full permissions in your security software (firewall).


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

See "Basic Troubleshooting: Make a new profile":

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
