Q: I use Firefox as the default browser on Windows 10, and I've recently had the program crash at random times when it's idle. Is this related to Microsoft's decision to block Firefox from replacing Edge as the default browser in Windows 11? How can I avoid switching to Edge?

A: Your unexpected Firefox crashes on Windows 10 and the difficulty of making Firefox the default Web browser on Windows 11 are separate problems.
