One irritant I’ve seen with Firefox over the last several years is that on Windows 10 it always crashes on quitting. I’ve submitted all the crash reports religiously and have briefly looked at some of the bugle bugs that they’re linked to. As per suggestions online I’ve even disabled history clearing on exit. But it doesn’t seem like there’s enough focus on reducing the crashes. Where I’m not doing enough is to run it in safe mode and figuring out what happens. I don’t have the time and energy to do that. So I’ll continue submitting the crash reports in the hopes that the different causes get addressed and make it more robust.
