Thanks for the response!

So,

I click the link. I click "Add", and Mozilla says addon could not be downloaded due to connection failure. Nothing appears in browser console.

Downloading an addon gives me "Download failed. Please check your connection." on the Addons site. In console, I get:

  Events to handle the installation initialized. BigInteger.js:27
  [GA: OFF] sendEvent {"hitType":"event","eventCategory":"AMO Addon Installs Download Failed","eventAction":"addon","eventLabel":"uBlock Origin"} BigInteger.js:27
  Error:

In the studies, I have https://i.imgur.com/fqrd5Jo.png. I enabled it, and have tried setting both first run, and the update interval is set to 21 (to try and force it to update it quickly).

Hmm, what happens if you right click and save-link-as on the .xpi link? Or if you download it via curl or wget or something?

Edit: That studies image looks like it has already been installed, which is weird if your extensions aren't back...

OK, so... I right clicked, saved-as and then ran the XPI... and that worked. So thank you for that suggestion.

As for the studies image, that's only half of the fix according to the blog post [1], mine is only verification-timestamp, not signing-intermediate-bug.

Glad to hear it worked.

You're right about the image, that's weird, I can't think of any reason why the verification-timestamp one would be necessary.
