If this chatgpt's website embedded into firefox's UI comes to firefox I might just have to find a different browser though. It's just an obscene giant embedded ad for a company.
They way to make this not an ad would be to
1. Remove any and all branding, chatgpt should not be mentioned, hugging face should not be mentioned, openai should not be mentioned, etc.
2. Make there be no way to pay for it.
That's what they did with translation, where they embedded something actually useful and not just a webpage into the UI in a way that a browser extension easily could if people actually wanted this "feature".
It's no different than when Mozilla began promoting certain websites, e.g., via "tiles". Around 2015, it formed a "Content Services" team to develop ideas around promotion and advertisement.^1 This included hiring an "advertising expert". IMHO it is strange for a web browser to be promoting specific content on the web but others might find it normal. The text-only browser I use does not do it, command line TCP/HTTP clients do not do it. Early graphical browsers did not do it. Regardless of whether it is appropriate or not, to deny that this is advertising is, to borrow the term from AI-speak, hallucination.
