When did you request that firefox back up the content to your profile? Bear in mind that a nontechnical user has no idea it does this, and a technical user only realizes it does this after reading the code or experiencing a crash. You "requested" this behavior implicitly by using firefox. So any behavior firefox has, now, or in the future with data you input is implicitly something you requested.

If firefox starts backing up your profile to a mozilla server, encrypted, you requested it. If there is an additional encryption key that lets mozilla decrypt it and sell it to OpenAI, you requested it.

Also, I am requesting that firefox send this post to HN by pressing the reply button. By the terms of firefox's ToU, this gives Mozilla a license to this content. That license is not limited to the duration of the http call if other firefox behavior that I have "requested" uses that content later. Perhaps they will scrape my comments from HN and use their content in targeted ads that firefox will display to me later. All allowed by the ToU.
