It's random and can happen at any time. I've tried all firefox, beta, developer, nightly. All have same results. I also tried disabling all add-on's and still happens Actual results: firefox will go black no matter what tab I switch to. Expected results: nothing

This happens to me. Same thing.

Just wanted to add, this only happens when you acceleration is turned on in advanced options. Problem stops when disabled.

I'm getting this on Windows 10 x64 (x64 nightly build, e10s enabled), without the flash plugin enabled. Hardware acceleration is on, and I have the latest drivers for my AMD HD7790 GPU.
