Perspectives missing from Firefox Add-ons site

Going to https://addons.mozilla.org/en-US/firefox/addon/perspectives/ results in Oops! We can’t find that page and I could not find another source for the addon.

This project hasn't been updated since 2016, so probably (I haven't actually looked) isn't a webextension, so it probably wouldn't work anyway.

Would some funding help? I cannot promise much myself, but maybe I could organize a fundraiser.

Perspectives used XPCOM to access information about certificates, which, to my best knowledge, isn't possible, and is not supposed to ever be possible with WebExtensions.

I can't remember the current state, but there has been some work on SSL APIs in WebExtensions in Firefox. There was basically nothing when they made the transition, but a lot is there and I think anything missing is probably on the todo list.

Edit to add: Proof of concept WebExtension: https://github.com/april/certainly-something

Certainly Something seems to use web​Request​.get​Security​Info() which indeed gives the relevant info; so looks like I was wrong. The only thing missing seems to be a way to override an error.
