The issue described in this article applies to Windows only.

Firefox version 33 includes a new feature called Off Main Thread Compositing (OMTC) which is a faster way of loading webpages.

The Mozilla community is continually improving this feature and are working hard to fix a known issue: if you are seeing a black or blank screen when you visit some sites, here's what you can do to fix the problem in the meantime:

  1. Press the Shift key while starting Firefox to enter Safe Mode.
  2. If the problem does not occur in Safe Mode, turn off hardware acceleration and then start Firefox in normal mode.
