> UPDATE: We’ve seen a little confusion about the language regarding licenses, so we want to clear that up. We need a license to allow us to make some of the basic functionality of Firefox possible. Without it, we couldn’t use information typed into Firefox…
Uh, yeah, that's exactly the problem. Mozilla shouldn't be allowed to use all the information I type into Firefox at all. Mozilla doesn't need any rights for Firefox to process my data locally on my behalf, or even for Firefox to send my data to third parties on my behalf (ex. instant search suggestions). Those aren't Mozilla using my information; those are me using my information using Firefox.
They would only "need" extra rights to collect data and process it on their servers for unspecified purposes. They do legitimately process some data on their servers, such as Firefox Sync data, but that's already covered under the Mozilla account terms of service. There's no need for a broad license for all data going through Firefox.
