firefox-43.0-1.fc22.x86_64 removed support for browser add-ons which are part of Fedora (as opposed to downloaded/curated by Mozilla). Please restore support for locally-installed add-ons. This affects packages such as mozilla-noscript-2.7-1.fc22.noarch and makes them unusable with Firefox.
It turns out you can set xpinstall.signatures.required to false in about:config to restore the old behavior. Perhaps this should be the default for Fedora.
New update (43.0.3) has the addon signing temporary disabled by upstream (Mozilla).
Created attachment 1121298 [details] Allow unsigned addons in /usr/{lib,share}/mozilla/extensions Debian carries a patch that allows unsigned addons in /usr/{lib,share}/mozilla/extensions (see attachment). Perhaps this patch should be added to Fedora as well?
Let's see if Debian will ship this patch in their branded browser. If so we can do the same in Fedora.
IMHO, while this patch fixes this particular bug (i.e., add-ons Fedora itself ships), it is not a sufficient solution for the problem as a whole. It limits support for unsigned add-ons to add-ons installed as root to system locations, preventing their installation through the normal browser mechanisms for add-on installation.

Kevin, talks are ongoing with Mozilla around how best to both allow add-ons and also to protect the user from malicious extensions (which are fairly common these days). No absolute consensus has been reached, but as a temporary solution, this is a considerable improvement. Also, it *could* be argued that the right to install an unsigned extension really does belong only to the root user of a machine, since A) they could do so anyway, since they already have privilege to install a modified Firefox and B) they are assumed to be a trusted, knowledgeable administrator of the system. That said, as noted elsewhere, I agree that the ideal case is for the user to have the ability to make their own choices, but at the same time I want them to be able to make properly-informed choices. That's a difficult balance to strike and one that we are actively working on finding.
