CentOS

"One or more installed add-ons cannot be verified and have been disabled"

Mozilla aware and are working on the fix. https://bugzilla.mozilla.org/show_bug.cgi?id=1548973

Here is an article on the situation. At the bottom of the article is a description of a temporary fix from Mozilla involving "Allow Firefox to install and run studies." This appears to be some sort of patch upgrade rather than a full upgrade of Firefox. As we are running Firefox...esr on CentOS I wonder if this applies to our browser?

At least on my Fedora 29 machine it has helped to install the hotfix from Mozilla manually:

Cannot test CentOS 7 in the week-end, so this has to wait until tomorrow.

I enabled the "feature" on one CentOS 7 virtual machine after making my post. I later suspended the machine for the evening. This morning all addons seem to be working again. On another machine where I did not enable the feature the addons are still disabled.

I copied my profile from the working Firefox installation to the broken one and the addons are again working.

If you are running ESR, you can go to about:config and toggle xpinstall.signatures.required to false. Don't forget to set it back once there is an actual fix in place.

Thanks!

Mozilla has fixed the bug and released ESR 60.6.2, which includes the fix: https://blog.mozilla.org/addons/2019/05 ... n-firefox/

But we still need to wait for Redhat to pick that up and rebuild and release their version before it can be rebuilt for CentOS.

Red Hat will likely be posting a fix on or around 5/21 when ESR 60.7 is dropped. In the meantime, Martin Stransky at RH has built the 60.6.3 release as an RPM and anyone can download and install it. It's working great over here:

I'm puzzled - 48 hours after the issue first surfaced, it disappeared as quickly with no action on my part and on all my CentOS machines/logins. Admittedly, my Firefox (by default) is set to keep Firefox updated. Is this why?
