ecosia: add search engine to ff nightly (using opensearch)
ff nightly will not work with the current ecosia extension. the opensearch form is also not loaded(?) automatically, and searching through the use of keyword is not conventient.
i found the opensearch url of ecosia: https://www.ecosia.org/opensearch.xml
and adding it through the webconsole (ctrl+shift+k): window.external.AddSearchProvider(engineURL);
fixed my problem (using "https...." as the engineURL).
