All extensions disabled due to expiration of intermediate signing cert

To re-enable all disabled non-system addons you can do the following. I am not responsible if this fucks up your install:

Open the browser console by hitting ctrl-shift-j

Copy and paste the following code, hit enter. Until mozilla fixes the problem you will need to redo this once every 24 hours:

    // 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();

Edit: Cleanup up code slightly...

// 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();

what did I do wrong? (It's all Greek to me)

What version of firefox are you running?

Apparently beta and nightly need to change `Components.utils.import` to `ChromeUtils.import`.

But anyways, don't use this now, use the semi-official fix of clicking on this link and letting it install: https://storage.googleapis.com/moz-fx-normandy-prod-addons/e...

This is the fix Mozilla has published to be installed via shield studies, but skipping the shield studies part. You can be sure it's not malicious because it is signed by Mozilla... and if your browser installed unsigned extensions you wouldn't be looking for this solution in the first place.

I installed the fix, nothing happened (my extensions still don't work)

After using the .xpi file?

Have you tried reinstalling the addons? I know it's less than ideal, but on one of my installs firefox had decided to uninstall the addons after disabling them (I think because it updated firefox version after disabling them). If it did that I don't think there is any way to get them back short of reinstalling.

Yes, I installed the .xpi file, firefox still says my extensions are unsupported/unverified.

Reinstalling seems to work, but there are certain extensions that have data I do not want to lose. For example, if I reinstall ubock origin, I will lose all of my dynamic filtering rules.

Possibly you just need to force it to reverify again. If this is still the state of things try setting `app.update.lastUpdateTime.xpi-signature-verification` to 0 in about:config, and then restarting your browser.

But no guarantees. Do you have reason to believe the addons are still installed?

That worked, thank you!

As a side note, the value for that setting got reset after I restarted firefox.

Also, I uninstalled the fix by simply removing the extension in about:addons. Is this the correct way to do it?
