The way of fix in the comment is really useful，once again:

Just replace in settings:
http://www.google.com/searchbyimage
to
https://lens.google.com/uploadbyurl
,and
image_url=::$URL:: to url=::$URL::

makes it easier for me to search any anime-related images

Хорошо что расширение не ограничевается одним лишь Google.

todo

It works exactly as I want it to.

it's good but yandex started have caption check
