For users of the 136.0 Release version on Desktop, we're now rolling out an out-of-band update to the interventions addon, see bug 1951479. The update rule is live, and the fix will delivered in the background, usually within 24 hours, but it can sometimes take longer, depending on the client.

It turns out that the website does some kind of Android-detection in order to block Android devices, which they do not support. Unfortunately that detection thinks Firefox on Linux is Android, and so we'll need to update our intervention to handle that case as well. I'll attach a patch shortly to address this.
