Hasn't been updated for a while, and indeed seems to not work anymore.

not working

As someone else said on another review, it works if you have this installed too:

https://addons.mozilla.org/en-US/firefox/addon/google-images-restored/

Tested on FF 93.0 on 2021/10/27.

У меня не работает

Doesn't work on latest Firefox.

Blödsinn, öffnet nur Bilder in neuem Tab, sonst nichts. Das macht die Bildersuche auch von alleine!

Used to work perfectly. Google recently updated the way it shows images. If you download another addon that restores the old version this addon still works

Not work.

В Firefox 77.0b9 x64 и Microsoft Windows 10.0.18363.836 View image in Google Images 2.0.9 не работает, кнопки "View Image" и "Search by Image" в результатах поиска Google Images не появляются.

doesn't work

Doesn't work.

Broken. Remove this addon since there is another much better one that works.

Ne fonctionne pas !

Can also confirm. This addon doesn't work. Don't bother using it.

it doesn't work, it has one job. Display the view images button in google search and it doesn't do that.

No funciona, es totalmente inutil

It doesn't work, it useless.
