Five stars because obviously this is my problem, not the extension's, but...

Out of the box it works, but I can't figure out how to do any of the customization that would make it truly valuable. Like,

① How do I add a search engine? I can follow the instructions, but adding a link to, say, dictionary.com takes me to that address, dictionary.com, not to a search for the highlighted word.

② What do P and C stand for in the "Search Engines" chart?

③ Where can I ask questions like these? A review seems the wrong place, but "Homepage" and "Support site" both lead to the same github page, which isn't for a non-techy like me.

Wonderful addon.
Suggestion: Could you add an option to click on a search engine in context menu without the context menu disappearing (for example holding ctrl) so one can quickly put a word in different search engines without having to right click again.

top, but i like to have an option to open the new tab focused/front if i press [return]

By far, the best and most essential addon ever.

The best addon for quick research - I love it.
A must-have!

great job.

What an absolute genius of an addon this thing is!! It has so much utility and power that I dont think I have even scratched the surface on what it can do, and yet I have spent a long time adding engines and bringing everything I use often right to my fingers with a one or two click tasks! It is very easy to do but does require a little time spent initially, if you really want to use it to its potential. I can select text anywhere and then choose to send it by search to...imdb, tpb, kat, nfodb, rutracker...and that is simply for one type of file name, that of a movie. I did list them all of course but I also could send it to numerous review sites, subtitles downloading sites. The scope is HUGE!!
I also love the additional little feature - which I have always said SHOULD BE THE Default behavior, or at least an option, and that is to COPY ON SELECT of any text. Just like IRC and it truly makes this addon brilliant alone! The whole host of other features are too much to write about or I will be here all day. Please install this and do yourself a huge favour!

How did I live without this?

Love it! Simple yet very convenient

Super addon! Replaces several others.
