page jumping down
When I am on website, scrolling down slowly, the page suddenly jumps to the bottom and I have to scroll up to get back to where I was. How can I fix this?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

You may have switched on caret browsing. You can toggle caret browsing off/on by pressing F7 (Mac: fn + F7).
- Options/Preferences -> General: Browsing
remove checkmark: [ ] "Always use the cursor keys to navigate within pages"
Note that this is a Firefox accessibility feature.
