This plugin supposedly kind of does that. I remember a few years ago Google removed it from the Chrome store, which I took as a good sign.
I never gave it a go though so I don't know how well it works nor if it's maintained; not only am I a bit too lazy to try to do some of that research myself, I also don't browse that many different websites to consider I could have relevant data.
beehaw.org is back up. So lets see how long until that thread updates on this instance.
edit: Ohh.. but beehaw.org is blocking lemmy.world So what would that mean for lemmy.world? Would the normal behavior be that we can see the thread's main post but not any comment?! I thought it was the other way around though, that they don't get any content from lemmy.world but lemmy.world can still fetch theirs.
Yes, you are right. But it had 3 days to sync. The oldest comment is 3 days old. Here is the same thread visible from another instance, much more up to date. I hadn't noticed that beehaw.org is down though. That could explain it. I still find it odd that this instance would not have a single comment on this thread over these 3 days but... yeah I'll take that explanation for the time being, I'll check again when I notice beehaw is back up.
Do you know how the fediverse works regarding this?:
If we take beehaw being currently down as a possible explanation for not seeing any of that thread here then I suppose first the comments need to reach beehaw.
I may as well ask another question, any idea how I would find that thread easily on lemmy.world? I tried pasting the full URL in lemmy.world's search but didn't find it, I had to manually go into that community in lemmy.world's instance and dig through the history to find it. In this case I assumed I would be able to find it by searching the full URL since the thread already is visible in lemmy.world, even if with no comments.
The content of one instance can be very out of sync with another.
Example, this thread in kbin is visible here in lemmy.world, and at the time of writing, not even a 3-day-old comment shows on lemmy.world.
I have been subscribed to this community from beehaw in lemmy.world for those 3 days, which as far as I'm aware is the only pre-requisite to sync. But if syncing takes longer than 3 days...
