Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:

• Windows/Mac: Go to Help > Restart with add-ons disabled
• Linux: Run firefox -safe-mode in the Terminal/Konsole

If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.

Many site issues can be caused by corrupt cookies or cache.

• Clear the Cache Press the <Alt Key> to bring up the tool bar. Then; Tools > Options > Advanced > Network > Cached Web Content: Clear Now

and

• Remove Cookies Press the <Alt Key> to bring up the tool bar. Then Tools > Options > Privacy.

Under History, select Firefox will Use Custom Settings. There is a button on the right side called Show Cookies.

If there is still a problem, Start Firefox in Safe Mode {web link} While you are in safe mode; Press the <Alt Key> to bring up the tool bar. Then Tools > Options > Advanced > General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites and see if there is still a problem. Then restart.

I have the same problem. None of the offered solutions work. I created a new firefox profile with the -safe-mode and deactivated hardware acceleration but the problem is still here. I have a macbook pro with Intel graphics card on Firefox 29 and Ubuntu 14.04 64bits.

Done. Thanks.

Like someone shared on Twitter (https://twitter.com/darkhole/status/480807577643929600), for Firefox on Linux, you have to force WebGL using this link https://www.google.com/maps/preview/?force=webgl and there is no more black screen on Google Maps/StreetView! So I don't think it is a Firefox problem, it's just Google who should learn coding cross-browser... At least they have a working link until it's fixed.

Nailed it! I'll just run GMaps from a bookmark, if/when I want to use the new interface.

Thank You.

Good work
