Firefox Community Forum

I purchased Dell desktop computer, Windows 11, I installed Firefox, and I made Firefox the default browser via Firefox and the computer's settings.

I selected default dozens of times. Each time it stays the default for a while and then another web browser becomes default.

I then again select Firefox as the default web browser, both ways, and it stays that way for a long time or a short time. A few minutes ago, after the selection, the settings window for the app page flashed and Firefox was no longer the default browser.

I have Google Chrome and Microsoft Edge installed for the few times that Firefox does not work on a particular website.

What gives? Thank you

Everytime I close firefox I lose all my tabs and history gets erased. This just started once I created an account. I tried changing the startup options, logging out and logging in, google searches, nothing works so far.

There is no sound from my desktop Imac. It has Tahoe OS 26.5.1. I have checked the obvious settings, volume, mute, etc. What could be the problem? I get sound when using Safari.
