Why am I getting black boxes and lines in Facebook chat area?
I just installed the latest version of Firefox as well as the latest version of my graphics card drivers, and Adobe Flash Player. When I open Facebook, I get black boxes and lines all over the left side of the screen where my chat contacts are. I am wondering why this is happening and if there is a current fix to it, as it is rather annoying. When I hover my mouse next to or over the black boxes and lines, they move and continue to pop up elsewhere but only on the friends/chat area.

Hello,

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.
