I-Firefox Community Forum

I know Firefox is slow when opening Facebook. It's busy blocking all their crap. But recently it's been super slow and non-connective to many sites I visit often. I've Ookla checked my connectivity and their excellent. Logging into sites I've visited before is now taking a long time some having to be resent. IE: www.clevelandclinic.org, local government sites etc.

Why is Firefox so terribly slow especially on Facebook? I've been using it for many years and it's never been as slow as it is now!!! This is not progress, but decline...
