No, the culprit you are losing add-ons isn't your computer, or maybe your old FF, or dropping of Webextensions API. Twitter, Reddit, everyone is wondering what is going on. This Armagadd-on 2.0 has a simple explanation: Mozilla forgot to renew certificates, and so add-ons are failing like if they were not properly signed, because technically they are not. Even signing of new add-ons is down (see comment 9). Great weekend at Mozilla HQ!
Some workarounds, until they clean up the mess, include playing with the computer clock (NTP? forget it) or disabling signature checks (not possible in default releases).
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:66.0) Gecko/20100101 Firefox/66.0
Steps to reproduce:
Wait until it's past midnight on 2019-05-04 UTC.
Actual results:
All addons got disabled due not having valid signature.
Expected results:
If the signature was due to expire, it should have been renewed weeks ago. Not all extensions were disabled. Fakespot and Google Scholar Button were left in their disabled state.
Some reports on reddit says that they had their clocks a day forward, but they may be just early canaries for the actual widespread issue.
Going backwards in time allows installation from AMO (Mozilla Add-ons) but do not remove the unsupported mark from the add-ons already installed.

Workaround: Go to about:config and set xpinstall.signatures.required to false

The intricate web of corporate lobbyists, military interests, bankers, intelligence agencies and other non-elected (sometimes non-government) entities that control the country outside of the political process you learn in middle school civics class. Oil companies, tech giants, the CIA, Goldman Sachs, all are entities which could be labeled part of the "deep state".
It's inaccurate to describe it as a singular entity with a unified ideology and motive; it's more inaccurate to pretend that it doesn't exist.
Is that straight enough for you?

Of course the establishment ass-suckers here would mod this 'troll'. This might as well be the green site.
