Sometimes I can't even scroll up and down a page, copy and paste or even type without HORRIBLE lag, any fix?

Have you tried starting Firefox in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode
If no improvement using Safe Mode, do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed?

and

Also, what security software is running on that system?

Just solved this issue on my FF 54.0.1, Win 10, dual core, 32bit system aka "ancient system", by removing Ghostery. Startup times went from 20 seconds to 5 seconds, no longer experience the slow downs, scroll judder, Firefox freezing, and other assorted issues on websites. Gmail is useable for me again!

Should you want an ad blocker, try the uBlock addon. Works for me.

Which version of Ghostery was that? Wondering since I'm still running the v.5.4.11, last version before all the serious complaints started. But I have noticed the various issues you're describing with my FF52.2.1esr, so will disable Ghostery and see what difference that makes.

My system autoupdates so it was likely the current version of Ghostery.

Yesterday, on a machine that is rarely used with Windows 7, FF 47 and some version of Ghostery, removing Ghostery had a major positive performance increase for FF. Firefox self updated to 54, then uBlock Origin was installed.
