Open Teams links in edge PWA, for all other links, use firefox (Linux Ubuntu)

Teams on Linux is currently only available as Progressive Web App (PWA). However, PWA are only supported in chromium-based browsers. For a multitude of reasons, you might not want to use chromium-based browsers as your default browser. This script opens links to teams in the PWA while opening all other links in firefox.

Finding PWA app ID and setting up the script

1. Install edge / chrome / ...
2. Install PWA for teams
3. In edge / chrome , navigate to edge://apps or chrome://apps, respectively.
4. Click on detailsfor MS Teams PWA
5. Create Shortcut..., select Desktop
6. The desktop file will be created on your Desktop, now we can retrieve the app-id.

• the file name contains the app id ~/Desktop/msedge-APPID-Default.desktop
• or you can read the file content: cat ~/Desktop/msedge-APPID-Default.desktop and see it there

7. copy the app id into the custom_browser_opener.sh script
8. Find the path to edge / chrome:

• whereis microsoft-edge
• whereis chrome

9. copy the path into the custom_browser_opener.sh script
10. Save the script at your favourite location e.g. your home location
11. make it executable: chmod +x ~/custom_browser_opener.sh

Register the Script as a URL Handler

1. Create a .desktop file for the script. For example, yourname-custom_browser_opener.desktop, Note that the name must contain a vendor prefix separated by a dash (-)
2. Replace /home/yourusername/custom_browser_opener.sh with the actual path to your script.
3. Register the .desktop file with your system:

xdg-desktop-menu install /path/to/yourname-custom_browser_opener.desktop
xdg-mime default yourname-custom_browser_opener.desktop x-scheme-handler/http
xdg-mime default yourname-custom_browser_opener.desktop x-scheme-handler/https

yourname-custom_browser_opener.desktop

[Desktop Entry]
Name=Custom Browser Opener
Exec=/home/yourusername/custom_browser_opener.sh %u
Type=Application
Terminal=false
MimeType=x-scheme-handler/http;x-scheme-handler/https;

Unfortunately, this does not work too well after the "New Teams" update...
Don't expect a fix in the near future.
