Re: [SOLVED TEMPORARILY] ALL Add ons suddenly stopped working in Firefox 66.3

What I did is completely removed the repository version, downloaded the tarball directly from Mozilla and extracted to ~/, then referenced the new location with the launchers. This allowed the extensions to download. Had to import bookmarks, reset preferences, etc.
I will keep the standalone version and do future updates by downloading directly from Mozilla. I like the idea of standalone
applications that need no installation anyway.

Hi, folks.

A lot of people told a lot of things on the expired certificate, on the problem which it causes (most Firefox add-ons and themes disabled since May 4th, 2019) and on possible temporary workarounds.


The officially recommended temporary workaround which will re-enable the disabled Firefox add-ons and themes can be found here:
Update Regarding Add-ons in Firefox
Any other workaround may or may not conflict with the future final solution, which Mozilla will come up with sooner or later.

So my advice will be: Stick to the official Mozilla workaround to re-enable your disabled add-ons and themes.

Cheers, Karl

I don't know when the actual fix was published, but I found an accidental fix 12 hrs ago. I was attempting to install a new different add-on to see if it's going to work. The add-ons came back immediately as soon as I picked the new add-on I was going to install.

This workaround doesn't work on Firefox 59.0.3 and older. :(
I also tried to install the fix as stand alone, doesn't work either.
link: https://storage.googleapis.com/moz-fx-n ... signed.xpi

Temporary workaround which works, is to start the add-ons through about:debugging and start them one by one thru Load Temporary Add-on button, and just wait for the fix.
Nothing is impossible, the impossible just takes a little longer to complete...
It is like it is, because you do what you do, if you hadn't done as you did, it wouldn't have been as it is. ;)

What worked for me:
In Preferences>Privacy and Security>Firefox Data Collection and Use
1: Uncheck: Allow firefox to istall and run studies, close firefox
2: Open firefox check: Allow firefox to istall and run studies, close firefox
3: Waited for a while, reopened firefox, got my extensions back

Which "study" is supposed to fix it? I've just turned studies on, and the only one showing is "prefflip-push-performance-1491171" and that has done nothing. about:config xpinstall.signatures.required False is the only fix that has worked for me.

At first which version of firefox is installed:

Code: Select all

firefox --version
Mozilla Add-ons Blog
Please note: The fix does not apply to Firefox ESR or Firefox for Android. We’re working on releasing a fix for both, and will provide updates here and on social media.
To provide this fix on short notice, we are using the Studies system. This system is enabled by default, and no action is needed unless Studies have been disabled. Firefox users can check if they have Studies enabled by going to:
  • Firefox Options/Preferences -> Privacy & Security -> Allow Firefox to install and run studies (scroll down to find the setting)
Check if Hotfix is installed Home <->.mozilla <-> firefox <-> xxxx.default <-> extensions

If you had taken the time to read the official Mozilla blog post Update Regarding Add-ons in Firefox carefully, then you would know which "studies" have been created by Mozilla to bring the refreshed certificate to your system that re-enable currently disabled themes and add-ons. :wink:

It has all been explained in the linked blog post including screenshots illustrating what to do and the note that once the certificate has been received and the disabled objects have been re-enabled "studies" may be disabled again.

The steps explained in detail by Mozilla and by more than one user in this thread have worked for me on several Linux Mint systems within less than 10 minutes. Sometimes it helped speed up getting the relevant "study" to shutdown Firefox and start it up again.

HTH,
Karl

on Firefox 66.0.3 - - I've had to remove any add-ons,,
& then re-install them again. .. then they are working A.ok.

NB: didn't perform any of those mentioned 'Fix' either.
NB2: all of those Firefox Data Collection and Use - were already checked & not by myself.

Screenshot of the official solution (or rather: the settings that will allow the official solution to be applied to your Firefox):

After the relevant two "studies" (what's in a name) have been installed, you can disable that feature again.

I did read the link, but, time I was three quarters through it, I'd already determined that I had already performed all the suggested fixes. That'll teach me not to finish reading! Said study is now installed and working as intended. Hopefully I can turn this off down the road. I'll keep an eye on it on my other computers as I do not rely on Firefox on them, so, if it does not get fixed in a hurry, it isn't going to affect them too much.

A day and a half has passed... I hope that those idiots who was involved this accident are already fired but still there is no general fix.

On Windows it fixed itself after about 24 hours. Not so on Mint - so I went to config:about and fixed it myself. Depend on nothing/no one to do anything right these days - all follow the Microsoft model (just jamb everything down the user's throats) - end rant.

I was referring to Windows 10 - I should have mentioned that fact.

I suppose Windows 7 is a victim of no support from Microsoft! Just the continuing saga of forcing Windows 10 onto everyone - directly or indirectly.

My sole reason for using Mint is to get away from Microsoft. Difficult, as their junk even encroaches (poaches?) on Linux with Skype. Generally, Mint has been successful.

To that end, I installed Opera this morning. It is OK but nothing to write home about. My VPN will not work with it and I have no trust in the built in VPN of Opera.

There's an official fix for Firefox on Linux, which I posted about earlier:
viewtopic.php?f=47&t=293510&start=60#p1630124

Works fine. :)
