Abrowser's Get Add-ons broken

I can confirm that this is also not working on Trisquel 7, 64 Bit running the latest version of Abrowser (44.0.2)

Steps to Reproduce:
1. From the Main Menu click on Add-ons
2. This takes you to about:addons in the browser as expected
3. Clicking on Get-Addons shows the list of all available addons from trisquel.info/en/browser as expected
4. Clicking on any Addon link causes the page to refresh and the attached image to be displayed.

I checked the Browser Console and the HTTP request to the respective add on comes back fine (200), it looks like the page for any given Add on is not being rendered properly.

Workaround:

Going directly to https://trisquel.info/en/browser and installing Add-ons from there works just fine.

Confirmed on Uruk 1.0 i686
Abrowser 44.0.2
for Trisquel 7

Confirmed on my machine as well, Trisquel 7 64bit
