new messenger opens links in EDGE instead of default browser.

I tried an older version of the app and it didn't show the popup with the option for "not now," leaving me only able to upgrade or close the app.

That's strange, assuming your version is the same as mine (mine is 2150.23.211.0, downloaded from the link I shared - you can check your version in Windows Settings > Apps > Installed Apps > Messenger > [three dots] Advanced Options). Mine does try to scare me by saying, "Update by [some date] to continue using the app." But the date keeps changing to either the day the popup appears or slightly in the future, and it's an idle threat - the rest of the popup doesn't change and I can always click "Not now" and use the app as is. Here is a screenshot of the popup it gave me right now.

Can we please stop making comments that are just complaints against Meta and Microsoft? Let's keep the discussion practical, centered around the solutions/workarounds.

I will repeat my current workaround: For me, the older version of the non-browser app is working great (downloadable from https://messenger.en.uptodown.com/windows/download/1026550438). Every time I reboot the PC and the app is loaded as part of that process, it suggests upgrading, but I simply click "Not Now" and the popup goes away. (I know that others have described how to make it a Chrome-based browser app, but I use Firefox, which Messenger doesn't yet support for video/audio calling.)

I cannot find it at all and I looked for hours...

This does not work. I dont use Edge, EVER.

Can you receive calls on the DESKTOP version of FB messenger? I cant.
