[Trisquel-users] (Trisquel 8) Problems with installing add-ons in Abrowser

[svenerik_vn]

In Abrowser, when I go to "Add-ons" and try to install the "Dark Backgrounds  
Switcher" I just get directed to this (see screenshot) and no add-on is being  
installed. I have tried various settings in the "Preferences" mainly in the  
"Privacy and Security" section like turning on and off the "Block pop-up  
windows" feature etc.

Has anybody else had similar struggles in regards to installing add-ons in  
Abrowser
