I love this addon. Recently google change reverse image search with lens. This addon has an option internal page in contextual menu in 3 dots right side of name in Firefox Addons (about:addons)
Select google and update with this config:
Search URL:

Search Variables (One per Line):
url=::$URL::
Finally click in Update Options button.
and now is fixed.

최고의 이미지 검색 부가기능

it was great but it just doesn't work anymore.

for google img search
just setting the url to "https://www.google.com/searchbyimage"
and insert a variable "sbisrc=1" (or2nd safe=off)
everything goes on :p

I found this for Google Lens

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

No longer works on google, great otherwise and i hope they fix it
