Does this also solve the 100% cpu usage on retina screens and the complete locking of macOS every now and then? How long does nightly stuff usually take to get into the final release?

Have any details? I have a retina screen and don't have any CPU usage issues.

  There are many bugreports known to Mozilla already. Here's mine: https://bugzilla.mozilla.org/show_bug.cgi?id=1407536 https://bugzilla.mozilla.org/show_bug.cgi?id=1407536

  AFAIK, it's a known issue with retina screens and scaled resolutions. If you use the default resolution, you should not see any issue.

    The default resolution has been a scaled resolution for years now.

      I think GP means non-integer scaling

        So do I. My MacBook Pro came out of the box supersampling at 3360x2100, or 1680x1050@2x. The screen is only 2880x1800.

The Firefox release schedule is pretty fast. This stuff should be in the beta release due out today, and the stable Firefox 70 release due out October 22.

> How long does nightly stuff usually take to get into the final release? You can try it out now. Open a terminal: $ brew cask install firefox-developer-edition $ cd ~/Library/Application\ Support/Firefox/Profiles $ ls -l (Determine which directory is your current profile directory. It should be recently modified and end with .default-release. $ cp -R this directory to .dev-edition-default and start Firefox Developer Edition.) Then in about:config put gfx.compositor.glcontext.opaque to true. I have to say that with a lot of tabs Tree Tab Style is still taking up a lot of cycles. Up to the point it (nearly) hangs. At such point, I switch to Sideberry which does not, use OneTab, and start from there. Perhaps setting browser.tabs.20FpsThrobber to true solves this. Trying that out now.

  Firefox Developer Edition is not the same as nightly from what I understand. Setting gfx.compositor.glcontext.opaque to true makes firefox unusable as alerts aren't readable (might be theme dependent). The only setting that you need to get FF to work on macos with a retina screen is the 'low resolution' mode trick. But then all text, etc isn't as smooth. I am now running some tests with the new nightly, so far it seems like it fixes the issues and I am very excited about this!

      according to @whimboo[0], these specific changes will land later this week on the developer edition. [0] https://twitter.com/whimboo/status/1168476885766082561 https://twitter.com/whimboo/status/1168476885766082561

FWIW, I get the CPU clobbered on a non-retina MacBook air, whereas FF works flawlessly on a retina one.

Never had this problem. At worst some pages manage to spin up my fans.
