Was thinking about this basic feature missing from FF (like countless others), so surprised to find exactly what I wanted.

In the settings of Popup / icons behavior
Right mouse button click ＞ Open in new background
It opens with Open in new tab, right?
why?

This turned out to be an extraordinary addon! I love it! I've always wanted to be able to add search engines in a simple way without knowing programming and SSS gives me exactly that! :D I was finally able to add a context menu search for Urban Dictionary. :D :D

Edit: I was wrong. This addon is not just extraordinary, it's EPIC!!! Once you figure out how to add new search engines, you can use it even as a translator. Guess what this address does to the selected text. :D

Search URL сайта КиноПоиск: САЙТ.ru /s/?level=7&m_act[what]=item&m_act[find]={searchTerms}

Mega add-on for searching, downright indispensable!

Подскажите как выключить всплывающую иенюшку после выделенного текста?

Perfect

Awesome! Simple and practical, easy to reach between the fingers, clever thinking

Great! Just one feature I'd love to see...
Opening behaviour: Text selection+click on selected text (left click)

Best extension ever! I use it constantly, it makes finding info and searching things so easy.
