Since nightly and release are affected, beta will likely be affected too.

I can reproduce this on Desktop in Responsive Design Mode, and I can confirm it's just UA sniffing, specifically in:
https://cfspart-idp.impots.gouv.fr/static/part/js/nav.js
The function "guess" there uses navigator.userAgent
to get your browser and version, and then cat()
uses the result of that to check whether your browser version is beyond the minimum supported one.
They have their minimum-supported-version per browser here: https://cfspart-idp.impots.gouv.fr/static/part/js/matrix.js
which has "firefox":102
but "firefox for android":0
(where 0
means no version is acceptable).
Anyway - UA spoofing as Chrome does successfully get us past this, so we could just ship a ua-spoofing intervention here.
