The problem is due to the t=trisquel being hardcoded as the default search
engine in the browser during compile.
You will find that the keyword.url is set here on line 74:
http://devel.trisquel.info/gitweb/?p=package-helpers.git;a=blob;f=helpers/make-ubufox;h=0c4c42197c038738e8d9ef45f9e07f4c06802822
However, the part you are referring to is actually set here on line 212:
http://devel.trisquel.info/gitweb/?p=package-helpers.git;a=blob;f=helpers/make-firefox;h=c81a6dee50f0058e093323c16341c0f87d91717f;hb=1c2440e15682d518a7349f76fa9ca0f9c0aae83d
It seems keyword.url was depreciated upstream by FireFox; not aBrowser.
The solution to remove this is fairly simple however. Go to
https://duckduckgo.com/html then in the opensearch box (the one containing
all the default search engines) at the bottom you will see: Add "DuckDuckGo
(HTML)". Click that and make sure to "Start using right away". Once you have
this search engine enabled you will find that the address bar (or keyword.url
as it was previously known) is now set to the currently set OpenSearch one.
You can change the address search at any time via the Search Engine dropdown;
and you can add/remove search engines from the Manage Search Engines window.
Hope this helps! :)
