I submitted a crash report: bp-28bfafdf-37b2-4a4c-b56d-19c690201216 I cannot start Firefox. It crashes with 30 seconds of attempting to open it. It crashes in safe mode, too. I refreshed Firefox. I have installed the latest Firefox (12/16/2020). I have uninstalled Flash Player. I have rebooted. I have no startup.*.cache file in my profiles directory. I have only startup_shaders. I do have two Firefox\Profiles\*.default-* directories. One was created years ago and the other was created on 10th December.

Chosen solution

Update McAfee. If the problem continues, disable it.
