Error if chrome is not installed

[Magikh42]

Launching the program chithout chrome generate an error
But opening http://localhost:3000/ in a browser works
However I need to switch to mobile mode (Ctrl + Shift + M) to use the app

The program is still dependant on chrome
Would it possible to make it standalone or at least Firefox compatible

For the fronted Karrelage relies on flaskwebgui, which currently only supports chromium based browsers (e.g. chrome, edge and brave). You can try experimenting with the browser path used to launch the application and see what flags can be used to adapt it to Firefox.
No plans to make it standalone.
