Not a good look for Firefox. Third partners and device fingerprinting clearly mentioned in the documents.
The move is the latest development in a series of shifts Mozilla has undergone over the past year.
The gecko engine and Firefox forks, such as Tor, Mullvad, Librewolf, and Arkenfox, are stables of private, open source web browsing.
In fact, Mozilla’s is one of the few browser engines out there, in a protocol-heavy industry that many say only corporate or well-funded non-profits can reliably develop.
What is more, daily driving the more hardened-for-privacy Firefox derivatives can be frowned upon by many sites, including your bank and workplace.
Mozilla’s enshittification leaves the open source community without a good alternative to Firefox, after years of promoting it as a privacy-friendly alternative to spyware-cum-browser Chrome.
It is abnormal for a free software project to have an EULA (i.e. a contract that one must agree to in order to install and use the software). This particular EULA does not seem to be as onerous as most but it may still place substantial restrictions on use.
The acceptable use policy, for example, covers much more than just crime (including a prohibition on “graphic depictions of sexuality or violence”). However, it also specifically refers to “Mozilla services” so one could argue that it doesn’t apply to normal usage of Firefox; however, the Firefox EULA also specifically claims it does. Is Firefox itself a Mozilla service? I would assume not under the usually understood definition of such, but it’s not really clarified.
It’s far easier to use something unburdened by an EULA, so I’m typing this from Librewolf.
