I'm trying out nebula because I saw your suggestion and honestly a year for $60 isn't terrible at all. But I'm having trouble finding creators (not because the app isn't good but because it seems a lot of the channels I follow on YouTube aren't on Nebula. I have two devices open actively going down the list of channels I follow on YouTube trying to find channels I want to follow on Nebula and so far I am striking out pretty bad. I hope I can get half the creators I follow on Nebula because so far it's pretty decent from what I have seen. App is easy to navigate and pretty polished etc.
Is there a way to view who's on the service (creator wise) before paying for it? Because if not that's the major flaw with it.
Could be UBO blocking cloudflare. https://forum.palemoon.org/viewtopic.php?t=31575
More likely though is that you're using Firefox with UBO and it is reading as out of date or a robot because it's using manifest V3 and it just doesn't like Firefox at all. I do believe someone posted the internet archive of the article though and you should be able to use that.
