Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Fred, for the last 30 minutes or so, I have been reading news. No jumping around on the screen. Does this mean, I always need to start Firefox in safe mode? Or is there an app or something that is causing this? Thanks for your help, Michael
If it works in Safe Mode and in normal mode with all extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) disabled then try to find which extension is causing the problem by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via one of these:
- "3-bar" menu button -> Exit (Power button)
- Windows: File -> Exit
- Mac: Firefox -> Quit Firefox
- Linux: File -> Quit
If you still have this issue with all extensions disabled then try to disable hardware acceleration in Firefox.
- Options/Preferences -> Advanced -> General -> Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
