Used to work, no longer does. Only shows Google's thumbnail image

It was going well until it became to return mostly google cache images (probably a defense by Google) as result for clicking on "View image" that had useless resolution/size and I'm forced anyway to go into the site and take the image by myself. But when it worked it was a great mod.

Do what it says, quick and easy.

This add-on stopped working weeks ago, as others have reported. Please correct this deficiency, and thank you.

Stopped working some weeks ago. Please fix it. Thanks.

Unfortunatelly stopped working. Tried disabling all other addons but still doesn't work 3:

stopped working

Works as intended in firefox 75 and 68.7 ESR on linux.
If it doesn't work, check other extensions (most likely adblockers), or your about:config.
Perhaps you mess up your settings while trying to "hardening" your firefox or something else?
Five star because it does what it says.

Please fix it. Doesn't work.
