why is firefox not working

[OBLAMA2009]

at youtube it cant play videos, you get all these black blocks that constantly prevent you from seeing the picture clearly. chrome doesnt have this issue and neither does the linux version of firefox , whummi s'pose tadoo?

Latest version? Flash up to date?

yep i think so 31.0 and in addons it doesnt say to update flash

Remove an re-install. Including profile data. Note you lose everything but it seems FF has become corrupted. See; http://kb.mozillazine.org/Uninstalling_Firefox

it just downloaded version 31 recently. does your firefox 31 play youtube without black squares all over the video? im wondering if this is just a bug they havent fixed yet

Youtube plays just fine in Firefox 31 for me on Windows 7 Professional.

It also works ok for me. Flash version 14.0.0.145 on Win 8.1
