We've encountered an issue in our environment where Mozilla Firefox when set as default (superseding MS Edge browser) will revert back to edge when performing the following sequence:
1. Log into non-persistent VDI session as standard user.
2. Open Firefox > Options > Check Always check if Firefox is your default browser + Make Default
3. Confirm Firefox has been set as default in Default apps settings.
4. Log off > Log on > Sign in as standard user.
5. Open Default apps > Confirm Firefox is still default web browser
6. Open Firefox from Start Menu/Desktop Shortcut
7. Witness Default apps automatically switch Firefox back to MS Edge
Any ideas why opening Firefox would trigger Edge to take precedence again?

- UEM 9.6
- AppVolumes 2.16
- Non Persistent VDI
- Firefox 31.8.0

Turns out it was the following line that was preventing it from sticking:

Thanks for the FTA suggestion, we've utilised it in the past.

Hi Dempseyy93,
I have written a blog post on how to roam FTA's successfully using UEM. You can find it here:

If you still have questions after this, please let me know.
