Firefox often reloads tabs without warning or closes active windows
Firefox 75.0 MacBook Pro
It often happens that while I'm typing, whether in an email or on an interactive webpage, Firefox will reload a TAB or completely close and lose my emails. I could be communicating via text on some website and suddenly find myself typing in the URL window after my active window/TAB was closed. This has been aggravating me for more than a year and I'm considering a change in browsers if I can't solve this problem.
