That's why https://addons.mozilla.org/en-US/firefox/addon/google-lens-s... exists. Google lens is exactly the kind of thing add-ons are for. Some people might like it, they should be able to install it, but it doesn't belong in the browser by default.

This is the same mistake they made with Pocket and I'm guessing it was done for the same reason (money) since they went with a Google product and not Bing Visual Search or for that matter letting users configure what service they'd like to use for image searches. This was pure bloat. It's no different from Windows adding candy crush to the desktop by default where the same argument "Some people play it and it can be removed!" does nothing to change what it is: bloat that nobody asked for.
