Getting a black screen after updating to Firefox 33 can be caused by a problem with hardware acceleration in Firefox.

Can you start Firefox properly in Safe Mode by holding down the Shift/Options key?

You can try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

Also check if there is an update for the graphics display driver.
