FF v 100.0.2: the button doesn't appear on Google image search pages anymore. This plugin doesn't work for me.

Firefox 100.0.2-nél: a gomb többé nem jelenik meg a képek mellett, a plugin nem működik.

Doesn't work on latest Firefox.

does not work at all

Не работает уже(( Does not work

Worked great until today, when I noticed Google completely changed image search (surprise surprise):

Not enough functionality. It should be also search by image

Does absolutely nothing that I can see. Non-functional.

Doesn't work. Almost always gets you a 404 error from Google. In the other cases the button doesn't respond at all. Button is too large as well. I'll be uninstalling it now.

Don't work

Stopped working after a few hours.

In order for it to work more than once, you have disable it then enable it for every single image. Otherwise it's just an extra "Visit" button.
