[Affected Versions]:

• Firefox Reality version 10 RC2 (17a313b)

[Affected Platforms]:

• Oculus Go - Android 7.1.2
• HTC Vive Focus Plus - Android 7.1.2
• Pico G2 4K - Android 8.1.0

[Prerequisites]:

• The Firefox Reality browser is open.

[Steps to reproduce]:

1. Disable Tracking Protection on more than 16 websites.
2. Open the "Privacy & Security" card from Settings and click the “Exceptions” button from the "Enhanced Tracking Protection" setting.
3. Observe the websites in the list.

[Expected results]:

• All websites that have Tracking Protection disabled are visible in the exceptions list.

[Actual results]:

• Some websites that have Tracking Protection disabled are not visible in the exceptions list.

[Notes]:

• The functionality doesn't seem to be affected as the websites that have TP disabled and are not shown in the exceptions list have TP disabled even after a restart.
• This issue is reproducible on random websites and is not reproducible each time for the same websites.
• Attached a screen recording of the issue here.

I have verified that this issue is no longer reproducible with the latest Firefox Reality version 10 RC4 (2999129) installed on the Oculus Go, HTC Vive Focus Plus, Pico Neo2 and Pico G2 4K headsets.
Now, all websites which have ETP disabled are displayed in the exceptions list.
