I am unable to select/install gnome-shell extensions when visiting https://extensions.gnome.org/ [filter settings: 'Compatible with: Current version'] as described in the FAQ section. I also searched for related posts (in this Forum), but could not find helpful information - although several people seem to be affected by similar issues.
- what first comes to the eye when visiting o.m. domain, all application icons and threads appear in a pale (i.e. faded) color
- when selecting either of these applications, a toggle (i.e. ON/OFF switch) is missing; no pop-up/red banner is shown, since the gnome-shell integration plugin is already activated
- remarkably, reviews as well are not loading (i.e. seem to continue to load forever)
- the 'installed extensions' tab [https://extensions.gnome.org/local/] is accessible, but empty
The system/setup I am using:
- Ubuntu (Gnome) 16.04.1 LTS 64-bit
- Kernel vers.: 4.4.0-45
- GNOME Shell 3.18.5
- gnome-tweak-tool is installed
- Firefox vers.: 49.0.2
- the gnome-shell integration plugin is enabled ['always activated'; confirmed in 'about:plugins']
- 'click_to_play' settings disabled(i.e. set to false) [in 'about:config']
Just to exclude putative conflicts, here is my output of apparmor_status | grep firefox
/usr/lib/firefox/firefox{,*[^s][^h]}
/usr/lib/firefox/firefox{,*[^s][^h]}//browser_java
/usr/lib/firefox/firefox{,*[^s][^h]}//browser_openjdk
/usr/lib/firefox/firefox{,*[^s][^h]}//lsb_release
/usr/lib/firefox/firefox{,*[^s][^h]}//sanitized_helper
/usr/lib/firefox/firefox{,*[^s][^h]} (2937)
/usr/lib/firefox/firefox{,*[^s][^h]} (3694)
I tried repeatedly to reload the pages/restart Firefox/restart the gnome-shell/reboot the system. No change so far.
Would highly appreciate any ideas what might cause the issue.
