- I started notice the problem when I first installed Firefox Quantum 61 on previous Mojave beta, the screen is all black and nothing seem to be clickable.

- Today after a blog stating that Firefox 62 was ready for Mojave I downloaded the update but unfortunately I am still getting the black screen window. except that this time when hovering on the windows I can actually click on some button like the one asking if I wanted to set firefox as default browser, note that this was blindly as I can't see anything.

I restarted Firefox in safe mode, all I get is a small pop-up window that is black as well.

I am using a MacBook Air early 2014 running the latest Dev Beta of Mojave. All the browser work just fine, chrome, safari and so on.

I am using the latest public beta of Mac OS Mojave (10.14 b10/11) and the latest firefox (62). When I open firefox, it shows a completely black screen with only the red/yellow/green buttons at top. No text, but I can do some interactions with the browser blindly (cmd + L to type a URL, check "about", open preferences, etc.) NOTHING is visible except when I begin typing in the URL bar, but it stays completely blank otherwise.

I have: 1. Completely erased and reinstalled firefox using AppCleaner. 2. Tried firefox safemode - still black. 3. Tried beta and nightly versions 4. Installing the last working version I had (which was 60 on Mac beta 9).

  • 5. Used a guest account - This shows firefox completely normal.

6. Reinstalled with fresh DMGs multiple times, still all black on my primary account. 7. No extensions should be installed, as I have completely erased and installed firefox.
