Ok

works at the moment with google whereas other similar addons don't: use search mode "select image".

This addon is absolutely great, but recently google reverse image search stopped working. When the results page opens there's no images just [https://www.google.com/imghp?sbi=1] in adress bar. Hope this issue wil be fixed. Thank you!

The search image using google doesn't work. Google page shows "Search by image is unavailable" as of November 24th 2022. It's been like this for a few days

Very useful!
