Thank you!

It should probably be filed as a separate follow-up bug: either we shouldn't ship about:certificate on android (obvious question: is there any way to load that on Android today?) or we should make it not depend on things that are not available, or we should make whatever it needs available on Android.

Sure, outside of automation / test running, it won't crash. But I bet the CSS file still isn't loading... and so the styling might look wonky if you were to open `about:certificate` with an actual cert. This is also what happens to some network error pages, cf. bug 1810039 and some of the bugs in the "see also".

Sure, outside of automation / test running, it won't crash. But I bet the CSS file still isn't loading... and so the styling might look wonky if you were to open `about:certificate` with an actual cert.

Edit: to be explicit about this, https://searchfox.org/mozilla-central/rev/64ddb621a0d3905fc2e3df475517d4163d377b22/toolkit/themes/shared/desktop-jar.inc.mn#59 and https://searchfox.org/mozilla-central/search?q=common.css&path=jar&regexp=false make it fairly straightforward to know the file just isn't packaged at all on Android (irrespective of fenix vs. xpcshell or w/e).
