Browser: Firefox Nightly 58.0a1 (2017-11-11) (64-bit)
OS: Ubuntu 16.04.3 LTS (64bits)
The extensions installs fine, but when I'm browsing a nuxeo instance, the icon does not activate, which makes the extensions completely useless
I've tested with Firefox 56.0 and it works fine. Maybe it has to do with Mozilla deprecating old extensions and supporting only web extensions?
BTW, Version 2.0 is marked unreleased in Jira although it's the one available publicly
