It worked great but recently stopped working :(

Good, I especially appreciate that it opens search in the next tab, instead of the end. But update Yandex search please, it does not work.

Works perfectly, very useful, has options to add/remove image search sites. It's great!

Works as intended, hence awesome.

before the new firefox this addon works very well

now with 57.0 a lot of setting options are missing

for example:

The focus of the results tab
Enable or disable the "All Engines" option
Enable or disable any of the available search engines

Excellent and helpful addon. Helps a lot.
