For user/password/jwt, it's needed to find the post id and the comment id in your instance's database. No instance will offer you free post/comment id search unless you happen to be a user.
Yes kbin is still not supported, I actually tried implementing it today but it doesn't have a proper sesrch API like lemmy (finding a federated post id in my local instance's databse). Kbin is still in beta so.
What link you were trying to redirecti? And open an issue here for better tracking: https://github.com/ManeraKai/fediredirect/issues
It does the same thing, recommending Firefox Beta or Nightly. For Tampermonkey, FediRedirect is a full browser extension not a script.
Yes, also Pleroma, Misskey, and all the other fediverse applications.
All you said is true if you are browsing through your instance, but if you were browsing another instance's website and saw a post or if someone sent you a link to a post in an instance you don't use, then you should figure out a way to see that post through your instance. In Mastodon, you go to search and paste the post link. In Lemmy, you do something similar. Those can be done but are quite tedious. This problem is what FediRedirect aims to make solving it more convenient.
(Username and Password) or (jwt) are required for resolving /post and /comment. If Username and Password didn't work, go to your instance's cookies and copy your jwt.
Let me show you some examples (you should be logged in to fosstodon, or it will redirect you to lemmy again):
Support is getting better over time.
How does it map the correct post on your own instance?
for Lemmy it primarily uses the API endpoint /resolve_object
Yes :)
It can now work on Firefox Mobile, but Firefox doesn't allow installing any extension for security reasons (idk if for compatibility reasons too), you can only install "recommended extensions". There's a way to install it on Firefox Nightly, but that's too advanced.
Some redirections aren't supported (bc Mastodon isn't fully compatible with Lemmy), and sometimes it doesn't work bc of a server problem (your instance doesn't federate with that link's instance). However, FediRedirect is still in beta, open any issue here: https://github.com/ManeraKai/fediredirect.
Also, why does it require my login credentials.
For lemmy:
(Username and Password) or (jwt) are required for resolving /post and /comment. If Username and Password didn't work, go to your instance's cookies and copy your jwt.
Same for mastodon, but it only has the read:search permission (scopes aren't implemented in Lemmy yet)
I'm watching over Freenet. It may solve this server resources problem hopefully.
