Click open link open non-default terminal

[MalcolmMielle]

Bug Description:

With Chromium (or Edge) and Firefox installed, even if Firefox is the default for the system, clicking on a link open Chromium (or Edge).

Edit: After some testing, I have realized that this only happen on the snap and not on the appimage. Furthermore, another snap I have has the same problem so it is probably not a Theia problem. I posted on the snapcraft forum about this issue.

Steps to Reproduce:

1. Install Firefox
2. Install Chromium
3. Make firefox the default browser of your system
4. Create a link in Theia either in text or in the terminal
5. Click on the link
6. Chromium opens

Additional Information

• Operating System: Ubuntu 25
• Theia Version: Theia 1.62.200

Closing because it is a snap issue
