WFM here, no black patches. Please, try with a new Firefox profile (https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles).
Looks like your graphics card is having problems, you could try disabling hardware acceleration (as a workaround)  firefox button > Options > Advanced > General > Uncheck "Use hardware acceleration when available"
Cork's suggestion worked. Didn't think of this because the site was working fine in Google Chrome.
If HWA is involved, could you paste and post the info of graphics section in about:support please.

The driver version is pretty old (8-9-2011), go to http://downloadcenter.intel.com/ and find the latest drivers. After the update, try to enable HWA again to see if the issue is fixed.
Shree, can you please update your status in this bug report? Please test as Loic has requested. Seems like this is definitely HWA related but we need confirmation that the latest drivers contain this bug. Unless we can get more information about this bug we'll have no choice but to resolve it as incomplete in two weeks time.
