had to disable this add-on. video clips on websites (eg: cnn.com) are no longer playing while this add-on is enabled. this only started happening in the last day so it is likely due to some update.

Good .. I use a custom solution

Great, I use it to set duckduckgo as my default search enginee. It only lacks the feature to set duckduckgo lite as the search engine. It's considerable faster in my region and it firefox dont sync search engines so i have to configure it all the time. (if you guys do so please also add per user config cloud saving plz).

thank you duckduckgo team for your service. FFFFFFFF
