Firefox vanishing on my macbook air
I just got this thing and all i want is to just be able to use google or firefox or something that isnt safari. Im just trying to take my classes for school and its so annoying in the middle of the lecture when we're supposed to be working, safari crashes or doesn't support canvas or whatever. I guess you can't just download it from the app store? you can't download like ANYTHING from the app store which is so dumb. So i finally downloaded and installed Firefox from its website or something but it kept DELETING every time my computer died. And the battery is crap so it died like twice and i had to go through the whole process of installing it and switching over my bookmarks and whatever three times. Im so tired pls send help
MacBook Air 13″, macOS 11.1
