Tabs crash, then I can't restart Firefox
Just installed Firefox on Windows 10. When the installation finishes, the browser window shows two tabs, both crashed. Trying to access any URL also results in a crashed tab.
If I quit Firefox at that point, then attempt to restart the program, I'll get the spinning circle for a few moments, then nothing -- it just won't run again. The installer file will run again, but I'll get the same results.
