In no way do I want a baked in Firefox feature to send website context to a 3rd party system. We have extensions that can do that with user consent and control.
This is a very good point. While it is a browser and can be used on unethical websites Mozilla itself does not include those unethical websites in Firefox while here Mozilla are listing unethical model providers in Firefox.
I'm glad they're not deeply integrated into Firefox. This means it would be nice if the dropdown allowed for a custom URL or even local mode perhaps running through openwebui.com.
