Cursor speed is insanely slow only in Firefox

Out of nowhere, my cursor speed in Firefox has slowed to a truly unusable crawl. I refreshed a page and it was suddenly inching along at worse than a snail's pace. I'm using a USB trackball mouse. This is only affecting Firefox; no other applications have this issue. Using Windows 10.

Here's what I've tried so far:

  • Restart Firefox
  • Started Firefox in Safe Mode
  • Restart computer
  • Create a new profile in Firefox
  • Check my mouse's firmware
  • Try a different mouse

There was another question about this years ago, but the accepted answer about accidentally enabling a Windows accessibility feature doesn't say which feature it is or how to disable it (if that's indeed the case). The link also seems to redirect to a generic accessibility page.

Does it still happen with the ESR version (115)?
