Why are all my pages loading so slow?

It might be worth checking if any security software is interfering or perhaps an old addon is slowing things down. Could you please follow the steps here: Fix problems connecting to websites after updating Firefox and restarting into troubleshooting mode to Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems to eliminate any usual culprits?

No troubleshooting data was captured for this question, do you use any VPN or antivirus or phishing/malware protection on your system?

NONE of the suggestions worked. I did fix it. Dropped Firefox for Chrome life is smooth.

Wow. Not only doesn't firefox work as web browser anymore, but your support forum clears itself before we can submit comments.

Mozilla, you should go back to making working software. The fact that virtually every single thing I every touch with the Mozilla name on it seems to be badly broken is really annoying.

Anyway, yes, to recap the post your submission form just randomly deleted before I could even post it, I agree with OP.

Firefox is technically not even a web browser anymore, since the job of a web browser is to load web pages and so often Firefox seems to have other priorities. And no recommended fix, here or in anything that can be found in google, ever helps, except for quitting Firefox entirely and restarting it. Which is becoming a pain to have to do several times a day.
