You surely do accept that every browser in existence needs to access the data used to display web pages (they are downloaded and the DOM built and rendered locally).
They never had published terms before but the browser is doing the same things right now to function that they didn't legally spell out before.
Legal are famously bad at writing in plain language esp when describing technology functions unless skilled in both areas or in a joint team - Mozilla aren't alone in that.
