    Default Web Browser not sticking

    Dempseyy93 Novice

      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?

       

      Details:

      - UEM 9.6

      - AppVolumes 2.16

      - Non Persistent VDI

      - Firefox 31.8.0
