I used to use Super drag but it's not fully working anymore since the last update and don't seem to be maintained anymore so to replace it i use your addon and the selected search addon.
I really like DragLinks. It's simple and efficient. It's seems to work fine but for some reason, it's not working for me on the mozilla addons webpage.
It would be great to see an option to select text and drag to search in default search engine or google by draging right or left to open in foreground or background. Maybe a box that pop up with multiple search engines. Thank you for this very useful addon!
