Can't install Firefox themes

When I go to Options>Personalization>Own Theme I can’t install firefox themes. No themes load up initially and if I put in a address such as Document Freedom Day 2015 – Get this Theme for 🦊 Firefox (en-US) in the search bar I get an error message that says it cannot open https://addons/allizon.org/en-us…, which is some other url and then the url I just put in is there too, as they are combined together, one after another. It seems like that the default url is wrong and it’s not letting me search other urls, as it’s combining the two. Am I doing something wrong or is there a way to change this default url?

Thank you for your time!

Hi

Indeed… Some bugs (e.g. tdf#101629) have been reported and are currently being resolved. Thank you for the report.

Regards

Me too. Same symptoms.
