Firefox Choppy and Slow Fix
2015/2016
Firefox/Chrome Choppy Scrolling-
Hey all. I've been having smooth scrolling issues in both FF and Ch. Seems a lot of others do too. I installed the Smooth Scroll extensions, disabled extensions, tweaked Chrome's and FF's Flags, screwed with Hardware Accel... etc. Although some helped, none made the choppy scrolling issues disappear completely. I have a recently new laptop- 5th Gen Processor, 900 Series VidCard, 16g Ram and an PCIe SSD. I thought it cant be performance problems. I scoured the net looking for resolutions. Found none. Then BAM--!!!
Your Mileage May Vary with this-- I am a power tab user. I do multiple searches opening a lot of tabs before I go back to check them out. The more tabs, the worse it got. I had always let Ch and FF manage popups... but they have got so bad I installed uBlock Origin on both browsers.
No more smooth scrolling issues!!! Seems loading background links with Ads and Popups were sucking the life out my browsers! No more. I even disabled the Smooth Scrolling extensions and it still was as smooth as a baby's butt.
Good luck!
