firefox-69.0.1-1.fc30.x86_64 from koji lags here terrible and procudes a lot of cpu-load on every non-trivial website, just to note and vaoid it amking it's way to updates-testing at all
Do you use X11 or Wayland Firefox version? Also can you try latest 69.0 build? https://koji.fedoraproject.org/koji/buildinfo?buildID=1379577 You can also test latest build without disabled DoH: https://koji.fedoraproject.org/koji/buildinfo?buildID=1379562 Another option is to use gecko-profiler to profile the performance: https://profiler.firefox.com/ Thanks.
X11 on KDE downgraded for now to firefox-69.0-9.fc30.x86_64 the 15 minutes i had 69.0.1 alo the idle cpu laod was very high
Sorry I don't understand. Is firefox-69.0-9.fc30.x86_64 better than 60.0.1 or not? Also can you look at "about:performance" page to see which page/addon consumes the CPU?
