This looks great! Any plans to open source it? Not that it's all that hard to pop open the .xpi to be fair.
Also minor suggestion: it looks like the archive.org API always returns non-HTTPS URLs (e.g. https://archive.org/wayback/available?url=https://old.reddit.com/r/programming gives http://web.archive.org/web/20230612074029/https://old.reddit.com/r/programming/). Might make sense to switch the protocol for the minor security boost.
Does anyone know of any communities for pigeons or capybaras (or tbh any other weird-but-cute critters)?
Edit: adding some as I find them:
