@keianhzo regarding the note from this issue where performing some additional steps, the app crashes that is also related to the issue when I relogin using the Login page from history. It seems that it can also result in the same crash if I copy the URL of the login page before loging in and then use it to relogin.
This are edge cases, but I wanted to point it out in case there is a fix for them since the #3612 PR only fixed the issue related to history, by hiding the login URLs.

@Softvision-RemusDranca Unfortunately there isn't much else that we can do, I've already brought this up with the AS team mozilla/application-services#3320 Hopefully we can get a fix soon.

I have verified this issue and it's no longer reproducible with Firefox Reality version 11 RC6 (e4f476e). Now, the Log in page is no longer affected by this behavior and it's not displayed in PB.

Tested on Oculus Quest (Android 7.1.1), HTC Vive Focus (Android 7.1.2), and Pico Neo2 (Android - 8.1.0).
