Adobe Flash causes it to get bogged down and freeze a lot.
I notice sometimes after awhile FF will become slower at responding - when typing a post for instance the gap between pressing one key and the next and those characters being displayed will increase to a noticeable delay of around 50-100ms until I close and re-open the browser. Doesn't seem to matter if its 2-3 tabs or 20-30 tabs and definitely stuff like flash content can cause it to happen quicker.

I like to stop it auto-starting (Plugins -> Flash -> Ask to activate).
It's amazing how many sites use it for no apparent reason (for tracking I assume).
Did this on an old Macbook recently and turned it from painful to fairly usable again.
Another thing to add, FF55 will bring big improvements when you have loads of tabs: http://www.techradar.com/news/firef...uge-numbers-of-tabs-leaves-chrome-in-the-dust
It's already in the beta channel, but should be coming out on the release channel in a couple of days (the 8th this month on the schedule).
browser.tabs.remote.autostart : true
browser.tabs.remote.autostart.2 : true
dom.ipc.processCount : 4
what is a firefox maintenance script ? (crash protection auto-save ? clearing the cache speeds up that, and can increase the period)especially Firefox maintenance scripts
does wonders, for me chrome is a speed over resources choiceThe Great Discarder
0.1.2
Automatically discards unused tabs to free up system resources
Never had this issue myself and often have pinned Netflix and Prime Video tabs open when watching stuff on and off, as well as multiple youtube tabs from subscriptions I watch through as and when.
So if the new FF update brings huge gains, things can only get better!
How old is your FF profile, and have you ever cleared the cache/history? I clear it all once a year as it just builds up, out of habit above all else.
