  1. Solved: The system clock was set correctly but I changed it anyway then changed it back to normal and that worked.

  2. I am having the same issue but in Developer Edition… All of my extensions, with the exception of one – the “New Tab Homepage” extension – are disabled with the message “… could not be verified for use in Firefox Developer Edition and has been disabled.”

    Computer time is correct. Windows 10, I have it set to automattically keep the time by default but I tried manually adjusting. Restarted Firefox, adjusted it back to the correct time, still the same… Tried again with several combinations of autmatically configured and manually entered times and dates and still nothing.

  3. Exact same here – just to add to the pool of people here. Have tried the clock reset. Making it more likely that an update triggered this?

  4. Another “me too” here. My date-time is set correctly and I don’t see any reason to change it. I’ve restarted FF but to no avail.

    I’m going to be upset if I’ve lost any config data for my extensions!

  5. I’ll add another #metoo. I looked away for a minute and when I came back all my extensions are disabled… WTF is going on here?? Mods, can we get this NOT marked as solved since the thread is full of others having the same problem with no success?

  6. Another “me too”. Had Firefox open and all add-on’s suddenly disappeared and are now treated as legacy. No additional add-ons can be added. Windows 10, Firefox 66.0.3 (64-bit). Changing the clock hasn’t worked so far.

  7. Wtf happened? So many of us experiencing the same with all the add ons whacked. And supposedly there was no update.

  8. Not solved. Not only are all my add-ons obliterated, I can’t download anything else without getting a bogus “download failed.”

  9. I was so confused because I had a video on in the background and I heard an ad, which I haven’t had happen in years… I’m sure they’ll fix it soon.

  10. Just happened to me an hour ago. Googled it and came across this page. Resetting my clock didn’t fix it.

  11. ah i have the same problem 😐 could it have something to do already with the changes Firefox announced to it’s Add-on policies ?

  12. Likewise. Every attempt to reenable my add-ons results in a “Download failed. Please check your connection” error. To make it more frustrating, many of my Add-ons are perfectly compatible with Quantum.

  13. Yeah, I just got hit with it as well. Tried resetting the time and even completely restarted my comp. Still nothing.

  14. Thought I was the only one in this mess.

    Tried doing everything I can think of. Won’t even let me download a replacement from the add-ons store

  15. Jesus, looks like they just nuked everyone’s extensions judging by the comments. 5/3/19 ~8:45pm EDT

  16. Chiming in with the other few dozen people to say I also just encountered this. Was in the middle of a youtube video when suddenly an ad popped came up and a notification came across saying some extensions have been disabled. There goes all of my add ons, including RES which is a bummer.

    Reply
  17. Same. I didn’t auto update FF. I’m still on 66.0.2. So nothing changed FF side here. Tried the time trick. No change.

  18. Without adblock, the internet is unusable. I’m going to have to spend all evening setting up a new browser. Anyone have any recommendations?

  19. My firefox just updated and I am now an unamused victim to this as well. My browser and my add-ons were fine before the update. I remember a past long ago where we had to live without these fancy things and looking at my browser does have a nostalgic feel to it. However, I don’t care for it. This is not a flash back in time that I am feeling remotely delightful about.. The clock-fix didn’t help here either. I’d like to go back to the future now, please.

  20. Same here, it’s all gone for no reason 15 min ago. :/

    Hope uBlock origin settings won’t be lost… have to admit I feel kinda naked without https everywhere, lastpass and youtube enhancer added to the browser… waiting for them to fix that problem, I’m migrating to Brave.

  21. Same here, guess I’ve made my last donation to firefox I’ll ever make. Time to finally move onto a new browser I guess. Firefox just gave Chrome the largest increase in users ever.

    Reply
  22. This is related to signatures. My guess is a problem at mozilla because it’s so widespread.

    As a temporary workaround I disabled signature checking and things are back to working. It’s in about:config xpinstall.signatures.required. This is NOT a good permanent solution. But it got my firefox back to working properly.

  23. Just hit me too. Giving me flashbacks to the crap that happened before they changed how extensions worked a while back and disabled every single add on I used and I had to do days of work to find replacement plugins, almost every one of which was inferior to the ones I used previously. I’d go back to Chrome and say enough of this crap but I really don’t want to use Chrome either. But Firefox just became nearly useless to me because of this.

  24. This is bad, i was working normally on Firefox until suddenly all extensions were disabled because they do not meet current Firefox standards, with these companies it seems that slowly you feel like your Device isn’t yours anymore, if the extensions were working normally and they stopped without me updating or making any changes that means that they do whatever they want without even giving you an option to choose to keep using them or not, now i cant use very important extensions because they just decided that.

  25. Just got this. Moving to using Vivaldi until this silly situation is resolved.

    Seems that a certificate has expired, which begs the question as to why this wasn’t caught before? I can imagine plenty of annoyed users at a time when Firefox can’t afford to annoy them…

  26. Read this.

    Apparently this is Mozilla again . I’ve only just recovered from their damn framework upgrade and now they’ve gone and disabled all my freaking add-ons again. No warning. No transition period just crapping on us all again from a great height

    Don’t they get it? Without the add-ons Firefox is a pile of crap! Are they run by the biggest morons in the whole of the IT Industry?

  27. Problem: the certificate they use to verify addons expired.

    Solution 1: Set your system clock back a few days (temporarily).

    Solution 2: Go to about:config and set the “xpinstall.signatures.required” flag to *false*.

    In either case, keep an eye on the below page, and once they fix the problem, revert your chosen solution (for security’s sake): https://bugzilla.mozilla.org/show_bug.cgi?id=1548973

  28. I was using Firefox normally until 10 minutes ago. When the clock changed from 10:59 to 11:00… all add-ons got disabled, but RES.

    I didn’t restarted Firefox, or updated anything. Was using normally, then My theme, and other add-ons got disabled.

    Firefox is getting on my nerves with each update. Why they insist in brake everything I like about this browser with every update?

    Seriously… just fix security issues and things like that. Holy shit.

    EDIT: Oh My Fucking God… Mozilla’s own extensions got disabled. This is priceless. WTF is Mozilla doing?

  29. I’m so sick of FF screwing me everytime they update! Mod toolbox, RES, Tampermonkey, Adblock are all down. This is ridiculous.

  30. I found a workaround for general release version (the one that everyone calling you for help with Firefox has) since disabling extension signature checks doesn’t work for release.

    Problem is due to an intermediate CA for the extension signing cert expired, and thus, all certificates signed by that CA (Mozilla’s extension signing cert).

    You’ll need to know the default profile name (there is usually only one, so it’s easy for users to pick it in the browser).

    FF -> Tools -> Add-Ons

    Right-mouse on the Gear icon to get the menu. Select “Debug Add-Ons”

    Click on “Load Temporary Add-On…”

    Browse to your profile’s extensions folder:

    e.g. C:\\Users\\\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\.default\\extensions

    or %APPDATA%\\Mozilla\\Firefox\\Profiles\\\*.default\\extensions

    You can temporarily load the extensions one-by-one in “debug mode” (you don’t have to launch the debugger).

    That’s as good as it gets until Mozilla deploys the replacement intermediate CA for their extension signing cert or finds some other fix.

    Firefox 66.0.3 64-bit on Win10.

  31. Which part of \*if it ain’t broke, don’t fix it\* do people not understand? I’m so disappointed.

    Also, not even an option to opt out? What has firefox become? Windows?

  32. Glad I’m not the only one. Pissed me off, too, because fuck Firefox for randomly shutting my shit off without my permission – some of us actually rely on these extensions to get work done.

  33. Total suckage…
    For my work eficiëncy I rely on some bookmarking and tracking plugins…All is fucked now…IS there a way to rollback updates ?

  34. We all know Mozilla Firefox sucks. If I place this comment under their discussion forum it would of been banned by now. They’re trying to be a Google Chrome except they keep on fk’ing up on every subsequent updates since day one. That said I am not surprised to find all my add-ons has disabled. Nothing uncommon, just another failed.

  35. Mozilla is rolling out a temporary fix using their “Studies system” (aka Normandy). I can confirm it works after enabling Data Collection (ie “Install and run studies”) and restarting Firefox. If you’ve disabled Data Collection, you will not get the fix.

    You might be able to force the fix by going to about:config and setting app.normandy.first\_run=true and restarting Firefox. That seemed to work for me.

    I also had to create a rule in my firewall to allow Mozilla’s pingsender.exe to go out on port 443

  36. What’s really galling is that this can happen without any changes being made to the install of Firefox… is it because Firefox actually has to “phone home” to confirm that add-ons are signed? If so, maybe we need an add-on to block this crap.

  37. Hope this is resolved soon. I forgot what an ad-riddled shithole the internet has become without adblock.

    Edit: https://i.imgur.com/bnLdteK.png This isn’t even the worse of it. This is the one site I managed to find that didn’t have ads flying in from the side to completely block content every time I scrolled.
