Whenever I use google docs, and try to select text, move between headings, format text, or type, my cursor will jump up significantly, either a few lines, or several headings depending on the action being performed. tested in other browsers, only occurs in firefox, and even booting it up in troubleshooting mode does not resolve the issue.

this is the only site where this occurs, so I thought it was an extension, but troubleshooting mode seems to indicate that it's not. Attempting to clear caches and reload the site doesn't work either. Currently using a wireless keyboard and mouse, not on a laptop with a touchpad, so it doesn't seem to be an input issue Like touching a pad indiscriminately. Advice?
