hi Coucou, the automatic background hotfix is only served to users on the normal release channel. esr versions will receive the fix in a regular program update (60.6.2esr) soon, so you should turn on auto-updates for this again...

Hi Philipp, Thanks for your answer, but again I may not update to 60.6.2, I want to stay on 60.2.0 as it's the latest version supporting bookmark description fields.

I don't get it, updates were turned off, how come a bug not on my end would need me to apply an update ?

hi, firefox 60.6.2esr will also still supporting the bookmark description field - those have been retired only in firefox 62 and upwards. so please perform the update when it's made available later on today...

unfortunately the bug that's causing all this hassle is on your end (in your local firefox installation). the signature verification mechanism for addons that was shipping with firefox for years contained a certificate with an expiry date ending on friday, so that needs to be replaced in order to rectify the situation.

Temporary fix : - Type about:config in your adress bar. - If it says "Danger !", answer "Yes, take the risk". - In the list, set xpinstall.signatures.required to false

Edit : It may not work for everyone. As philipp said : It should work with nightly, devediton, esr and some linux distro builds.

ALL your add-ons should come back in a blink of an eye.

You're welcome!

For you maybe. Doesn't work for me.

Do you run v60.6.2esr ? Sorry I was too enthusiastic seeing all my addons back with all their data after almost 24hours of limbo... I should have mentioned that it may not work for everyone. But it's still worth a try.

There was a Bug-A-Boo with a Certificate Expiration Date dealing with the Add-ons. There's a new FF Version with the main Fix, 66.0.4.

Mozilla Blog Post Update:
A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061).
There are remaining issues that we are actively working to resolve, but we wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week. More information about the remaining issues can be found by clicking on the links to the release notes above.
