You should try to uninstall and reinstall Firefox, let me know if it fixes.

Unfortunately it didn't work.

You can try to disable hardware acceleration in Firefox.

• Options/Preferences -> General: Performance
  remove checkmark: [ ] "Use recommended performance settings"
  remove checkmark: [ ] "Use hardware acceleration when available"
• https://support.mozilla.org/en-US/kb/performance-settings

Close and restart Firefox after modifying the setting for changes to take effect.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

Hello Amy,

Would you please take a look at this thread and see if the solution there will work for you as well :

Thanks for the help. The first option didn't work but since this is a work laptop I cannot check for updates. Could this be because I am using windows 7 and it has the option to upgrade to windows 10?

We posted at the same time - have you checked my post yet ?

Did you try to disable hardware acceleration in Firefox ?

Hi McCoy, changing the mouse settings didn't work for me, although seems to have made it less frequent. Cannot open regedit because of work computer restrictions.. I guess I will have to take it to IT. Thank you for the help.

Hi Cor-el, yes I did that but didn't seem to work for me.

Not giving up just yet .....

Please take a look at this thread (last updated July 15, 2019)

Is this only happening with the auto-scroll mouse pointer that opens with a middle-click or also in other cases?
