Doesnt work on some wikipedia websites. When it doesn't work the error doesn't give the extension name, doesn't fit in the viewport and doesn't give you an option to disable on that page eg km.wikipedia.org has no instance on wikiless so it totally blocks access with an error that is no help

It also is an all-or-nothing for families of websites so you have to totally disable it for all wikipedias if one isn't on the instance set.

There is also no bypass for if you want to login to edit eg fandoms or wikipedias
