Firefox has started blocking unsigned extensions

[pcause]

I run from Nightly, and I installed the latest and I just noticed that it is disabled. Firefox says it is disabled because it is unsigned. Mozilla announced intent to do this and apparently they have started to enable. If you use nightly or developer addition you can toggle (make true):

xpinstall.signatures.required

and install the latest from github. Mozilla site says that if you use released or beta this option isn't available.

Why don't you install it from here? https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/

[pcause]

I usually pull development releases so I've just pulled from github.

Maybe documentation should be updated to add the xpinstall.signatures.required fix for people who are installing the unsigned release.

While having self-hosted (i.e. hosted outside of AMO) extensions signed is possible, it still requires review from Mozilla. I think gorhill (when on a roll) releases new builds at a pace that is too fast – sometimes two in a day. Unless the review process is improved.

@AmrEldib

the xpinstall.signatures.required fix

This won't be possible in Firefox Stable or Firefox Beta after the next update.

I installed 1.0.0.1 from https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/ and it still lists as unsigned. Am I doing something wrong?

[gorhill]

uBlock Origin from AMO is signed, so you should not have any warnings when you install -- all extensions from AMO are signed.

[gorhill]

I created a development channel on uBlock Origin's page on AMO: scroll to the bottom, expand Development Channel.

My understanding is that this AMO-hosted beta build is signed, and it will auto-update whenever I push a new beta version. I installed it on the release version of Firefox 40, and it went fine.

[pcause]

I just went there and looked and the developer channel in the site says you can't install these versions of uBlock on released versions of Firefox. From what I've read released means released and beta. Not an issue for me as I use nightly, but may be for others.

[gorhill]

I know, but somehow I could install it fine on Firefox 40 on my side (Linux).

On the new uBlock development channel installed from AMO on Firefox beta (41). Extension updated earlier today. No warnings in addon-manager, no problems.

Fx 43 on win7, uBO from AMO dev channel 1.3.3b2
xpinstall.signatures.required;false

xpinstall.signatures.required;true

Doing the following worked perfectly for me on a new firefox (nightly and stable) install & profile:

Make sure to backup any settings from an install and remove uBO if it was installed from github.

Unfortunately, regular Firefox doesn't allow turning off this blocking.
Maybe it's time to switch to GNU IceCat…
