Which browser do you use?

Or just download the 66.0.4 which should be auto updated soon.

For me it fixed itself (most likely from Mozilla team) an hour ago when I started using the pc.

Another quick(er) fix: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/comment-page-6/#comment-226171
Works. You can even have Normandy (the "backdoor" into your preferences) disabled in about:config.

You should post the official workaround in the OP instead of that one: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/

I restarted Firefox and it worked a few seconds after it.

I turned studies on about 2 hours ago, still waiting for the fix to kick in.

Sure. They do warn that it's not an insta-fix though:
It may take up to six hours for the Study to be applied to Firefox.

Try this alternate solution then, it's semi-official.

I have been using Chrome for so many years that I forgot Firefox even existed.
No one using Netscape Navigator anymore? :P

I uninstalled it, and reinstalled it. Fixed the issue, plus it remembered all my saved logins, bookmarks, etc. It was weird.

I just had to toggle something in the about:config and everything was fine again.

This may be a valid fix, but from a security standpoint trusting a random certificate into your browser is not a good idea. Better to wait for Mozilla to provide their fix.
Comment has been collapsed.
I was careless enough to not think about it... can anyone look into the certificate to check if is alright?
Comment has been collapsed.
that's something to do prior than posting a public download link for a certificate.
i'd edit that description, if i were you.
Comment has been collapsed.
The above certificate is legit. If you wanna manually check:
- download the hotfix xpi file (hotfix-update-xpi-intermediate@mozilla.com-1.0.2-signed.xpi) you can find the link on reddit
- open in 7zip extract the file "experiments/skeleton/api.js"
- you'll find the certificate base64-encoded in a string: "MIIHLTCCBRWgA...<..snip..>..AT0zo4c="
You can export the certificate as DER file using:
$ echo <<..long-base64-string..>> | base64 --decode > certificate.deror convert it to PEM file (like the one supplied above):
$ openssl x509 -in certificate.der -inform der -out certificate.pem -outform pemAnd verify the certificate:
$ openssl x509 -in certificate.der -inform der -noout -text
$ openssl x509 -in certificate.pem -inform pem -noout -textwhich is indeed a Mozilla AMO root certificate for signing addons.
That being said, NEVER trust or install certificates randomly from the internet!

Can I use this method to put this certificate to FF 56.0.2 manualy as a solution? i installed this hotfix to firefox 56.0.2 but it deleted addons again anyway. Needet to use script to regain them:
// For FF < v57 >...?
async function set_addons_as_signed() {
Components.utils.import("resource://gre/modules/addons/XPIProvider.jsm");
Components.utils.import("resource://gre/modules/AddonManager.jsm");
let XPIDatabase = this.XPIInternal.XPIDatabase;
let addons = await XPIDatabase.getAddonList(a => true);
for (let addon of addons) {
// The add-on might have vanished, we'll catch that on the next startup
if (!addon._sourceBundle.exists())
continue;
if( addon.signedState != AddonManager.SIGNEDSTATE_UNKNOWN )
continue;
addon.signedState = AddonManager.SIGNEDSTATE_NOT_REQUIRED;
AddonManagerPrivate.callAddonListeners("onPropertyChanged",
addon.wrapper,
["signedState"]);
await XPIProvider.updateAddonDisabledState(addon);
}
XPIDatabase.saveChanges();}
set_addons_as_signed();

Also in this hxxps://files.catbox.moe/h0vakr.crt link there is good mozilla certyficate too?
Comment has been collapsed.
If you follow the steps I posted to extract the certificate from the XPI hotfix, you will get the same "certificate.pem" as the one posted above "h0vakr.crt". So yes it is good.
You probably just have to wait as Mozilla will release a new Firefox version containing the fix. I hear they are also preparing a fix for ESR builds.

Thank you for a reply.
I guess i can also install this certificate and if it is legit it should be safe?
Comment has been collapsed.
You can but again you are trusting a random person on the internet ;)
When it comes to security, paranoia is a good thing!

If you don't use add-ons, there is nothing to fix! ;)

Not only the ad flooding but some of the filters I use in ublock are against much nastier and it does get them. Also I use the Malwarebytes extension to nip things that could be sketchy.

That other (temporary) fix is pretty neat too (and at least doesn't require installing some unknown certificate): https://www.reddit.com/r/firefox/comments/bkhzjy/temp_fix_for_the_armagaddon_20_for_regular/

Thank you for posting this, saved me from having to go browse the internet without an adblocker on which is a scary scary thing.

I just installed Firefox Developer Edition, moved my profile from base firefox and allowed unsigned addons. Should have done that long ago, but was too lazy, so now I had a perfect opportunity.
Comment has been collapsed.
They have fixed it.
Did nothing and my add-ons are back.
Comment has been collapsed.
I use old version of FF 56.0.2 (before they removed support for some of my favourite extensions). Today was a total disaster. Was able to recover my profile and now it works, but I set different date - not sure what will happen tomorrow:). I wonder if they will make a general fix or only for newer versions? Ryptun does your fix will work also on old FF, maybe it will be only method to repair FF without changing date...

I'm still using Firefox 50.1.0 from December 2016 and I am only using that new of a version because that was the current version when I updated to Windows 7 from XP :)
I actually use Chrome for SG though, I use Firefox for everything else.

The issue seems to have been fixed on Mozilla's end.

Not sure if most of the community uses Firefox, or only Firefox users opened the thread to see the poll.
Probably the latter.
Comment has been collapsed.
Firefox user stats are mostly marginal worldwide now. Websites are not even optimized for it anymore, which is all on Mozilla for making poor choices and keeping going with them.

Anyone still having issues, especially with FF v. 66.0.3 on portable? Running this script that DingDong2 posted a reddit link to is what finally worked for me.
Comment has been collapsed.
in my opinion you really should edit your description.
awful idea to post a live link to download a certificate in a public forum.
