I use this extension multiple times per FF session; it's become an invaluable tool due to the ability to add a search for any site.
I love it!

Very usfeul addon but with cumbersome path to configuration panel (need to open all addons, search down for SSS and use manage options). A handy control panel icon directly on the pop-up would considerably improve the UX.

I love this add-on, I've used it since I found it a few years ago. It's so handy to be able to highlight text and have it automatically copy to clipboard. And as an added function, just under the selected text will be search engines and shopping site links (which you can customize), to instantly search those sites for the selected text. It's all so intuitive and seamless!

LOVED IT

Hands down my favorite add-on for everyday use. It is a perfect example of what an add-on should be. It's lightweight, customizable, and open source.

Swift Selection Search is nice.
But it closes the origin page and open the search in a new tab. o_O
WTH??!
The option to open in the same or a new tab without closing anything should be done.

I was once a happy man but this superb addon has made me hate myself.

I've only just now discovered this addon and I'm having to come to terms with the fact that I've spent so many, many years without it.

This addon has emotionally ruined me. It should come standard with FireFox. 5/5

This is the best add for search and its customizability is topnotch. I wish it could also allow to popup in a new private window too.

Зручно і швидко.
