    Recently I updated Firefox for OS X (Yosemite) from version 35 (I think) to version 38.0.1.

    When I load the browser everything is fine, but after using the browser not for long I start getting glitchy pixelated squares all over the window!:

    - When I scroll up/down they show up all over
    -When I hover the mouse pointer over a link, the bottom left link display is pixelated and distorted.

    Any ideas on how to fix this? Never had this sort of issue with Firefox before....

    since I run on Apple, so I can't compare to your situation.

    I think it's best to remove FireFox from /Applications and make
    a fresh start with a download from:
