new messenger opens links in EDGE instead of default browser.

WOW, Did not know that.
I can use this for so many other things.
Like CIG's Spectrum and so on.
Super usefull.

The correct solution was given above, but I think it missed one step. Unless you uninstall Messenger first, Chrome won't give you the option (at least for me)

1. Go to "add or remove programs" in Windows settings and uninstall messenger.
2. Open chrome
3. Go to messenger.com -- login if needed
4. Click 3 dots on upper right
5. Look for Cast, save, and share
6. Click Install page as app

The good news is, because the app is just an edge browser, using a Chrome browser it will look exactly the same as the app, except for being Chrome. Well... you may need to do Ctrl-scroll wheel to change the zoom level, or Ctrl-+ and -

Haven't read the whole thread, but it looks like that the new Messenger is basically just an edge app. If I kill edge, Messenger dies. Basically Facebook aren't bothering to make a real app, so it will always open links in Edge, because it's already IN Edge.

You might want to read a little more of the thread. Only recently did the app become connected with Edge, so you can use an older version (up to v. 2150.23.211.0) without that issue - up through that version it was an independent app developed by Meta that did not run on any browser, so it will send links to whatever browser you have set as your default. Uninstall your existing app and then install this: https://messenger.en.uptodown.com/windows/download/1026550438
