Hubzilla posts hardly work for me anymore on Firefox or Firefox ESR
Hello again,
A week or two ago, I've first noticed that, when I access my Hubzilla from Firefox ESR, HQ posts won't load anymore at all and the channel page would always (or almost always, can't recall with certainty if it worked once for me after a refresh) load only the pinned post and then nothing, no loading spinner either. Whenever I needed, I'd just fallback to Ungoogled Chromium, where everything works.
However, even after the update to 11.2.1 (I believe I hadn't updated before this problem started) and after I switched to the latest Firefox, the problem persists. With security extensions active or not, nothing changes.
I'm using these browsers on OpenBSD, but I don't believe it should matter, although the Firefox browsers and Ungoogled Chromium packages have different maintainers.
Where to start with debugging?
