I change to new PC from my old one the using dual core to New HP 600 G3 MicroTower with i5-6500 & 8GB RAM - 128 SSD In last week I was using Firefox as my only browser. When I'm opening 2-3 tabs or more then that, the scroll isn't work like regular and feel sticky, When typing it's not in the moment and have delay of 1-2 sec. I'm using only Dashlane & uBlock extension and none of them make it worst. I was try to close tabs with music from you-tube but it wasn't change a thing. In task manager it's showed up Firefox using about 900-1000MB Try to update all drivers, close background apps, but nothing helped..

Hi, this amount seems ok, 900-1000MB You can check these things please : 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.

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.

Please try : SAFE MODE

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder)
  • default toolbar layout is used (file: localstore-safe.rdf)
  • Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
  • hardware acceleration is disabled (Options > Performance > Uncheck to view)
  • plugins are not affected
  • preferences are not affected

I have got a similar problem with Firefox 64.0 under Gnome 3.30 (gnome 3.20 as well).

Firefox freeze for several seconds after clicking on a radiobox of the firefox interface, such as in 'Preferences' and the download dialog.

I finally found that this bug is caused by 'screen keyboard' from gnome Universal Access. When you hit a radiobox of firefox while gnome screen keyboard is enabled, the bug occurs.

So I can solve this problem by either disable screen keyboard or check the Prevent accessibility services... checkbox.
