From the new terms:
When you upload or input information through Firefox, you hereby grant us a nonexclusive, royalty-free, worldwide license to use that information to help you navigate, experience, and interact with online content as you indicate with your use of Firefox.
Seriously Firefox include many services, specifying the TOS for the entire browser is stupid.
What is worse is that people are asking for clarification and there is no response from Mozilla:

Yeah, they should have a general one that lays out their intentions, and then addendums for each service. It’s hard to tell which are intended to apply strictly to Firefox and which are intended to apply to other things, like AI, Pocket, Sync, etc.
Keep the base one small and tight, and then have specific exceptions for services that require them.
