DO NOT uninstall, change, or otherwise modify your plugins. Mozilla will hopefully fix this very soon

Your Firefox extensions are all disabled? 

That's a bug!

Some Firefox users started to notice that installed browser extensions were all disabled in the web browser suddenly. Extensions would display "could not be verified for use in Firefox and has been disabled" messages in the add-ons manager of the browser. Firefox would display "One or more installed add-ons cannot be verified and have been disabled" at the top as a notification next to that.

Affected extensions include LastPass, Ghostery, Download Manager (S3), Dark Mode, Honey, uBlock Origin, Greasemonkey, NoScript, and others.

Seems like one of their certificates expired. That is what I am reading on other sites. 😒

[AdvancedSetup]

Yes, but that doesn't seem right. If it really is a bad cert, it should have been replaced weeks ago. I'm sure we'll find out more about it by tomorrow.

I've got my ad-ons and extensions back using a fix released by mozilla, it uses the 'studies' option.

Got to- Options >Privacy and Security

Enable- 'Allow Firefox to install and run studies'.
(Restart Firefox).
After a few minutes your extensions should appear and you can disable studies again if you want to.

Otherwise it's a case of waiting until they release a fix in the normal channel.

[sysopa]

For everyone's info: we don't need to do anything if ""studies" is enabled (Firefox Preferences -> Privacy & Security -> Allow Firefox to install and run studies).

After activating it again all Add-Ons are back

[nukecad]

I just said that in the post above.

It's actually a 'hotfix' (2 hotfixes) that they have released in the studies channel to get it out quickly.

[Gt-truth]

GUYS , how do I resolve this problem with Cliqz web browser since there is NO studies option of this web browser software ?

for FIREFOX web browser it fixed itself

[nukecad]

I've just posted a link in the Firefox beta thread that applies the main hotfix without 'studies' so should work with FF clones.

Here it is again:

Uninstall it Gt-truth

Some users are reporting that they do not have the “hotfix-update-xpi-signing-intermediate-bug-1548973” study active in “about:studies”. Rather than using work-arounds, which can lead to issues later on, we strongly recommend that you continue to wait. If it’s possible for you to receive the hotfix, you should get it by 6am EDT, 24 hours after it was first released. For everyone else, we are working to ship a more permanent solution.

The latest available announcements on this topic are now being posted on the public Mozilla Add-ons Blog at Update Regarding Add-ons in Firefox, which confirms that the automated fix being rolled out via the Shield Studies feature does not apply to FF ESR (extended support release) editions, since the Shield Studies feature is not included in FF ESR editions:

Quote

"  ... 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..."

The following workaround for Firefox ESR has been suggested in many forums.  Type about:config in your address bar and click I Accept the Risk when you see the warning This might void your warranty!.  Then search for xpinstall.signatures.required and double-click the setting to temporarily change the value from TRUE to FALSE . Once a permanent fix is announced for Firefox ESR  users can go back into their configuration settings and double-click xpinstall.signatures.required to toggle the value back to the default TRUE.  See the Mozilla support article Add-on Signing in Firefox for more information about this configuration setting.

I tried this in my Firefox ESR v52.9.0 (the legacy version for Win XP and Vista) and Tools | Add-ons | Extensions now shows a warning for Adblock Plus and my other extensions (“<extension name> could not be verified for use in Firefox.  Proceed with caution.“) but they're all enabled again and functioning normally.

Has anyone tried reinstalling FF ESR v52.9.0 today with a new installer downloaded from https://www.mozilla.org/en-US/firefox/new/ ?  I was curious if the v52.9.0 installer from this download page now includes the updated certificate.  I just checked the 32-bit installer on their FTP site at https://archive.mozilla.org/pub/firefox/releases/52.9.0esr/win32/en-US/ and it looks like it hasn't been updated since 25-Jun-2018.

Just an FYI that Forum Moderator philipp posted instructions today in the Firefox forum thread “Add-ons disabled” problem in Firefox 52.9.0 ESR (32-bit) for Windows XP for manually importing the updated certificate into FF ESR v52.9.0 (the legacy version for Win XP and Vista) that fixed the problem in my own browser.  Here are the general steps:

1. Download the updated certificate addons-public-intermediate.crt from https://hg.mozilla.org/releases/mozilla-release/raw-file/tip/security/apps/addons-public-intermediate.crt (link is external).
2. In Firefox, go to Tools | Options | Advanced | Certificates | View Certificates, click Import, and select the downloaded addons-public-intermediate.crt file.  Click OK in the pop-up dialog box (i.e., do not check any check boxes).  You will see a new certificate listed for Mozilla Corporation named signingca1.addons.mozilla.org (see attached image).
3. Enter the advanced configuration settings (type about:config in the address bar) and search for app.update.lastUpdateTime.xpi-signature-verification. Right-click this setting and choose Reset from the context menu.
4. Re-start Firefox.

If you previously implemented the temporary workaround and changed xpinstall.signatures.required to FALSE in about:config, remember to change this setting back to TRUE after importing the updated certificate.  My understanding that this is a permanent fix but this procedure will likely have to be repeated if you re-install / refresh your FF ESR v52.9.0 browser at some point in the future.

At this point, might want to consider running Linux if you can't afford to update to Windows 10 - very difficult to keep running XP nowadays.

Upload the latest  version of Mozilla  hxxps://rocketfiles.com/windows/browsers/web-browsers/mozilla-firefox or at official website. Everyhting works on it. I tested Download Manager (S3) and  Dark Mode and they are working. Maybe the problem is with Windows?

Hi anthonydbarnes:

The latest versions of FF v67.0.x / FF ESR v60.7.x are not compatible with Win XP and Vista.  Mozilla ended support for the legacy version of Firefox v52.9.0 on my Vista SP2 machine in September 2018 and Mozilla had no process in place to automatically deliver the new security certificate that would fix my older version of Firefox.

This issue is now resolved.  The Mozilla blog Add-ons Disabled or Failing to Install in Firefox was revised on 14-May-2019 and now includes links to browser add-ons that are posted on the official Mozilla AMO store that will "resolve the expired security certificate issue and re-enable extensions and themes". As noted in Bugzilla bug report # 1550793, the bug fix was delayed for older versions of Firefox because Mozilla had to develop three separate extensions that would add the updated security certificate:

    FF 47 to 56: https://addons.mozilla.org/en-US/firefox/addon/disabled-add-on-fix-52-56/ 
    FF 57 to 60: https://addons.mozilla.org/firefox/addon/disabled-add-on-fix-57-60/
    FF 61 to 65: https://addons.mozilla.org/firefox/addon/disabled-add-on-fix-61-65/

I already followed the instructions in post # 20 of this thread to manually install the updated certificate in my FF ESR v52.9.0 browser so I don't plan to install the new FF 47 to FF 52 extension posted on the Mozilla AMO unless I hear there's a good reason to do so (e.g., that the certificate delivered by the extension posted on the AMO is actually newer than the one I manually imported on 07-May-2109).
