For some reason the only the scroll bar indicator becomes invisible and only appears when I have the mouse hovering over the location of the indicator in the scroll bar. I am able to see the scroll bars themselves, its just the blue indicator bar that is shown in the scroll bar that disappears . I tried restarting Firefox to see if might fix the problem but it didn't. I had to restart the computer before I got the scroll bar indicator back. But it wasn't long before it disappears again.

Any suggestions? I'm using the latest version of Firefox and Windows 7 Ultimate 64-bit.

Thanks

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do not click the Reset button on the Safe mode start window or otherwise make changes.

Try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

It may be that the theme you are using has a bug. There are some userContent.css fixes that may help that, but first try the default theme and see if that works okay.
