Using Nightly, and compared to IE where I don't have a problem, there are black lines across all pages of some forum installations. Have screenshot.
At first I was told it was my video driver, but maybe it could be the motherboard. However, IE on the same vBulletin pages does not produce thick and thin horizontal black lines, as shown in my screen shopt.

Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

It appears you are running 64-bit Nightly or UX. If you find that disabling hardware acceleration doesn't help, do you have a rough idea of when the problem started?
Yes! Disabling the hardware acceleration worked! Awesome.
