fedv.link bookmarklet
Bookmarklets are not a technology I use very often (mainly because of how Firefox now handles bookmark favicons, grr), but I suppose I've finally found a use for them for myself.
I'm sure someone else will have done this already, but here is an example of a bookmarklet using fedv.link to redirect from some Mastodon (or Threads?) page to that on one's home instance.
Will probably change this into a browser extension if I get the chance, so that it can have a proper icon on cromulent browsers.
