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

Don't have that problem.
youtube-dl means no ads, no pain, 10x faster load, and I can bookmark / speed adjust / etc. in my viewer of choice.
You're smart enough to use linux. Try youtub-dl, it's simple and effective, you might like it.

Thanks, funnily enough I can still watch the videos (and also now download them again using a firefox extension thanks to TFS) so maybe I should not have said COMPLETELY b0rked. It is the search, suggested videos etc. that aren't working and I find them quite useful (so shoot me).
Also, are you saying that Linux isn't appropriate for use by the general population? Grandma will be disappointed!

Grandma is old and wizened. She is certainly *not* the general public.

No. I meant "less intelligent people normally don't run linux, not because they cannot, but because they aren't clever enough to see the value in it."
By extension I thought you might see the value in a commandline downloader, where many people would dismiss it without even trying to evaluate pro/cons.
