libreom

Yeah I will add refreshable list of instances, custom lists probably not(extension stores has many restrictions on remote code loading)

No, yes, It depends- for my simple use case of redirecting embeds and links, it is probably faster by using declarativenetapi instead of heavier webrequestblocking api

Yes, Predirect currently chooses randomly from list of instances from farside/official(I'll make it updatable/refreshable in near future) or one custom instance (I'll also add editing list of custom instances in far future) [ofc if chrome store allows these two]. I didn't add libredirect/reddit due to ratelimiting problems and GotHub, anonymous overflow due to usability issues. I'll add search, maps in near future and also others. Predirect does distribute traffic by randomising instances so not an issue. Thanks for suggestions and contributions are welcome for any of these

The extension currently doesn't handle YouTube.de (unless it is redirected to YouTube.com) but you can choose your custom instance. I'll add more features soon

Libredirect is a manifest v2 extension (can't be published on chrome store) and has permissions for all_urls, predirect is a manifest v3 extension and only has permissions for necessary domains
