    Does someone have the same issue with Firefox ?

    Window immediately turns black after launching Firefox. Switching between light/dark mode makes no difference.

    Did a clean install on an Macbook pro 15 inch 2017 with Mojave

    Runs perfectly fine, FX 62.0.2 on 2017 MacBook with Mojave upgraded from High Sierra.

    Runs fine for me - the contrast seems very off but I can read it and write (as I'm doing now)

    Having this same issue and I haven't been able to find a solution yet :(

    Upgraded from High Sierra.

    So I think I found the issue, based on the fact that I didn't have it right after the upgrade. I didn't like the full-dark mode of Mojave at first so I tried the command from this post.

    I reverted the effect by doing
    defaults delete -g NSRequiresAquaSystemAppearance
    , then restarted.

    I have noticed that in Mojave the Firefox browser window now appears in all of my desktop spaces. In previous Mac OS versions it only appeared in the desktop space I opened it in.

    Has anyone else noticed this? BTW if this is seen as off topic let me know and I will post it elsewhere.
