Can you add the possibility to add other search engine (brave, mozilla firefox, duck duck go, écosia...) ?

I thought it has a selection option to select the specific part of a picture. But instead it selects the full picture to search.

not bad...

Buttons don't work in latest nightly and stable

It is difficult to use.

A competent enough add-on, works well. However I detest the beg screen that I was surprised with. I would rather not see such a thing, and can find no setting for it.

Edit to add: I accept that you may need support. I believe you should find a less galling way to get that support. I abhor having my day interrupted for even one second by a program I have already installed asking me for money. I will not be pleased if that screen shows again, and you have still offered no way to prevent it.
