After the Mac mini sleeps and wakes up, the firefox application that is open on the screen freezes and crashes. If I minimized the firefox application to the dock, it won't crash.
Firefox : 85.0.2 (64 bit)
MacOS : 11.2.1 (20D74)
MacBook Pro 13″, macOS 10.13
Disable sleep, it's a non-feature for later Macs.
Thanks for your answer. How can I disable sleep?
System Preferences > Energy, then check “Prevent...”
It didn't work. It wasn't about Mac's sleep. Firefox crashes/freezes after the screen turns off automatically.
Report it to Mozilla then https://bugzilla.mozilla.org/home. Good luck.
Firefox crashes on Mac mini m1.
