Firefox (a new up-to-date install) has been very crashy on my new computer -- PC running Windows 11. I ran troubleshooting mode and it shows 0 crash reports. On my old computer, I had 4 Firefox windows open, a half dozen extensions, ~200 tabs and it was quite stable. This brand new install is running one window, 3 extensions, a dozen tabs open, and freezes and crashes pretty much every time I try to read my email (or do anything else that involves clicking). How do get a stable Firefox?
