For the longest time ever I always felt that scrolling in Firefox didn't feel smooth compared to other browsers. Even my old MBP 15" from 2009 was scrolling smoother than my current Alienware 13R3 from 2017. I first checked other browsers and they didn't have this issue. Disabling smooth scrolling or hardware acceleration didn't fix my issue either.

However, the fix appeared to be simple. Go to About:config and find accessibility.force_disabled. Change the value from 0 to 1 and restart your browser. This fixed my issue with the slow and laggy feeling scrolling. I'm hoping the devs can incorporate a fix for this in the next update.

Hi, it can be turned off here without the need of about:config To be Checked and turned off unless needed for accessibility : Please : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check (put a tick in the box) the setting to Prevent Accessibility Services from accessing your browser.

If still having issues : Multi-Processor Support : Go to the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please. Note : Hardware Acceleration is for Video Card, Monitor to see if remain off or to turn back on.

Only Disable as last resort.

Multi-processor Can completely disable it this way in about:config : dom.ipc.processCount set to 1 browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false

Only move to esr if low ram and old system.

Firefox Extended Release Version : Firefox ESR does not come with the latest features but it has the latest security and stability fixes.

If do please :

Please let us know if this solved your issue or if need further assistance.
