Description of problem:
Firefox (firefox-52.0-0.7.el7_3.x86_64) does not allows you to install extensions from http://extensions.gnome.org/
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install the test version of Firefox 52
2. visit http://extensions.gnome.org/
page says: "We cannot detect a running copy of GNOME on this system, so some parts of the interface may be disabled. See our troubleshooting entry for more information."
Page should see which gnome version I use and offer extensions
I have several other extensions installed, and they are all enabled like it was in Firefox 45 ESR, however some stopped working, like: cliget (
That's NPAPI plugin and it should be enabled in final ESR52. They're going to be disabled in next ESR59.

Now that we should have almost final build https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=541255 I believe we can try this issue again, correct Martin?
Yes, the NPAPI plugins should be enabled in the ESR52.
I can confirm that this is fixed in firefox-52.0-1.el7_3.x86_64

Discussion on how to handle the removal of NPAPI support is in bug 1609200.
