You can open "about:config" and set "xpinstall.signatures.required" to false.
Just don't forget to re-enable it once the fix is out.
@fribbledom I tried that, but it didn't work - do I need to do anything else?
Maybe restart Firefox. I must admit I haven't tried it myself so far. I kinda don't dare to restart my browser right now, since I badly depend on a few extensions 😆
@fribbledom Does restarting break all your other addons?
Oh, so you still got a running instance and just wanted to install a new addon right now?
Tough situation, really. I probably wouldn't risk it.
@fribbledom @grumpysmiffy You can also install the fix directly, without „Studies“: https://storage.googleapis.com/moz-fx-normandy-prod-addons/extensions/hotfix-update-xpi-intermediate%40mozilla.com-1.0.2-signed.xpi (source) @hugo
@fribbledom @hugo According to this: https://bugzilla.mozilla.org/show_bug.cgi?id=1548973#c19 xpinstall.signatures.required works on Android but not on “proper” Firefox.
