I noticed that mouse zoom wasn't working in Firefox so I went to my add-ons and all my extensions have been disabled. I am getting a message that my extensions can not be verified by Firefox so there being disabled. I can not download any extensions either because I get a message that says "Download failed. Please check your connection". All other web sites work ok. All my extensions were fine with the new firefox(version 57 to the newest one) until today. Even ublock origin is disabled. Any one else have this happening?

Themes are also disabled. Somehow I am not verifying 3rd party extensions.. I have never had this happen in all the years of using firefox.

Restart the system
 
Just happened to me as well. I'm to high to deal with it now. I'll read this in the morning and play some games. :rockout:

right now I am using FF nightly build as temporary workaround as developer version do not enforce signature check on add-ons
 
I'm temporarily trying out Opera. Ublock seems to work with it.
 
I got the add ons working by doing this "In Developer Edition or Nightly, enter about:config into the location bar and push enter. Heed the warning and proceed to search for xpinstall.signatures.required and set it to false. "
Then I added a couple add-ons that I need. Like mousezoomer, really need that one. Fixed for now
 
I got this too. wtf

watching a youtube cooking video and get a giant fkn ad thinking wtf. See ublock origin is gone. go to install and firefox says "Download failed. Please check your connection. "


fkn bullshit

All my addons are gone and I cant remember some.
 
66.0.3 here, no issues.

This worked for me to re-enable addons.
To re-enable all disabled non-system addons you can do the following. I am not responsible if this fks up your install:
Open the browser console by hitting ctrl-shift-j (might need to set devtools.chrome.enabled to enable in about:config)
Copy and paste the following code, hit enter. Until mozilla fixes the problem you will need to redo this once every 24 hours:
Code:
    // Re-enable *all* extensions

    async function set_addons_as_signed() {
        Components.utils.import("resource://gre/modules/addons/XPIDatabase.jsm");
        Components.utils.import("resource://gre/modules/AddonManager.jsm");
        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 XPIDatabase.updateAddonDisabledState(addon);

        }
        XPIDatabase.saveChanges();
    }

    set_addons_as_signed();

I'm on 66.0.3 as well it took a couple hours for me browsing to show my addons disabled.

Not gone: merely disabled.

I got the add ons working by doing this "In Developer Edition or Nightly, enter about:config into the location bar and push enter. Heed the warning and proceed to search for xpinstall.signatures.required and set it to false. "

This worked for me as well, but doing it turned the addons on by itself: no need to add anything further.
 
I had same today. I uninstalled FF and did a clean install of latest version and had to reinstall my 3 extensions. Looks okay now.
 
Arch pushed an update today and I'm trouble free. Using the Developer Edition though, no idea of that makes a difference.
 
Mine's all back to normal again. I didn't have to do anything.
 
Likewise with me

EDIT: It just took a long time to decide that my add-ons weren't verified

I uninstalled Firefox and reinstalled it. Ver 66.0.3 64 bit
Still unable to download and install uBlock Origin extension.
 
Ublock Origin and Dark Reader stopped working on my phone today. Really hope they fix it soon or give us the option to disable the certificate check.
 
Got a fix for you guys needing adblocker.

Install adguard within windows or android its free for like 2 weeks as well. Enough time for firefox to fix there sh!t.

66.0.3 here.
No uBlock Origin or any extensions.
Hopefully mozilla will tend to this matter fast.
 
66.0.2 on my phone with the extension issue.

I literally read your post and then saw that mine was back at the same time.

Attempted to restore "xpinstall.signatures.required" in about:config to "true" again and it disabled my addons: returning it to "false" re-enabled them back.
 
I'm using Firefox 66.0.3 on Kubuntu 18.10. Simply going to about:config and setting xpinstall.signatures.required to false instantly brought back my add-ons.
