Suggest to search the image directly with google image search in right click drop box rather than having to save and drag image to search bar to do it.
Image Search on Chrome
In chrome, when you right click on an image, there is a popup menu contains find similar images. Here is not. It is good to have.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
I think such functions are the role of extensions.
As an example of an add-on for this:
If you prefer Google Image search, someone probably created an add-on for them, too.
(Note: similar ideas have been merged into this thread)
If you haven't already, consider checking out this extension. Been using it for a while, you can search images with Google and a few other services.
With such powerful extensions available, I'm not sure if there's any benefit in adding this to Firefox itself.
of course a lot of stuffs can be done via extensions, but its just way better and safer if it were supported locally where it shouldnt be too difficult
If it's going to put in firefox it has to be local if not use a extension
I'm not sure what is meant by "local" here. Local as in offline image search? Because I don't see how that makes sense.
The extension I linked above allows you to search for images in a frankly [ridiculous amount](https://github.com/dessant/search-by-image/wiki/Search-engines) of engines. It's also open-source, has over two hundred thousand users, and earned the "Recommended" badge on the Firefox add-ons page. I'd say it's decently safe and powerful, and it looks like even Mozilla agrees.
Sorry if I sound too negative. I definitely see possible benefits, especially regarding ease of use on mobile. I just struggle to see how a native Firefox implementation would be worth the spent time and effort right now, specially when highly request features like tab grouping are still waiting. But it'd be unfair to say the idea itself isn't worth it, just because I hope other priorities get more focus.
