1815079 - Links don't open in youtube app when adblock is turned on

Status: RESOLVED INCOMPLETE

(Firefox for Android :: WebExtensions, defect, P5)

Description

[Mb]

User Agent: Mozilla/5.0 (Android 10; Mobile; rv:109.0) Gecko/111.0 Firefox/111.0

Steps to reproduce:

I use firefox nightly (111.0a1 (Build #2015931435)) + addon ublock Origin. "open in app" button is active.
It happens with any adblocking addons like adguard.

Actual results:

Opening youtube links on website 'https://wykop.pl/' opens a new tab in firefox instead of opening youtube app.
Tuning off ublock addon or tuning off all filters inside ublock fix the issue.
It happens only with youtube links. For example imgur links open imgur app.
It might be connected with webRequest api

Expected results:

Youtube links should open in youtube app.

Could you please retest, and provide us more details: the exact link that the issue can be reproduced on, and the device you are testing on?
