Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat.

Description Oliver Ilian 2017-01-24 13:53:25 UTC
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):
firefox-52.0-0.7.el7_3.x86_64
gnome-shell-browser-plugin-3.14.4-53.el7.x86_64

Steps to Reproduce:
1. install the test version of Firefox 52
2. visit http://extensions.gnome.org/

Actual results:
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."

Expected results:
Page should see which gnome version I use and offer extensions

Additional info:
I have several other extensions installed, and they are all enabled like it was in Firefox 45 ESR, however some stopped working, like: cliget (

Comment 1 Martin Stransky 2017-01-24 15:01:11 UTC
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?

Comment 3 Martin Stransky 2017-03-01 07:43:32 UTC
Yes, the NPAPI plugins should be enabled in the ESR52.

Comment 4 Oliver Ilian 2017-03-01 11:26:43 UTC
I can confirm that this is fixed in firefox-52.0-1.el7_3.x86_64

Comment 5 Florian Müllner 2018-09-03 15:41:15 UTC
Marking as closed as of comment #4.

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