  • Yes, every browser caches resources that multiple pages of the same site use, unless the site instructs them not too.

    It is also the case that almost every modern browser does not share those caches between different websites, to avoid providing a mechanism for them to share data. This means that for websites, it is no longer beneficial to use CDNs, if it ever was - in practice, it was also the case that only very few CDN resources were actually shared between different websites (since they all depended on different versions or different CDNs).












  • There’s definitely the bureau kredietregistratie in the Netherlands.

    As far as I know you can’t “freeze” it like you describe, though you can request information on what is stored about you and who accessed it. It also costs money to run a check, and credit history doesn’t go back more than five years, doesn’t include your mortgage unless you missed paying that for longer than three months, and doesn’t include debts less than €250.

    Edit: also just checked, but the information is only shared with parties that share credit history with the BKR. I think that means that it’s basically frozen by default, i.e. only parties that are actually about to do business with you can access it, but I’m not entirely sure. They’ll at least have to do some kind of business, i.e. not be a generic data broker.





  • It’s a bit of a stretch to turn “may also” into “main purpose is”, but you’re right - that shows that indeed it’s not a big leap to use it for advertising.

    But no, as I understand it, this isn’t extracting sensitive data from users and then only keeping it in anonymised aggregate form - the sensitive data is handled on your device and never reaches Mozilla, and the anonymised aggregate form (i.e. the high-level category derived from that data) is the only thing that’s actually sent.

    And again, it’s always been an ad platform, it’s still the only proven way to fund development.

    I won’t comment on this acquisition, cause I have no idea what this company does.



  • Ah right, we’re talking different definitions of “Firefox users”. I meant that they’re not collecting data on specific users, i.e. there’s nothing on Mozilla servers that says anything about me specifically. The post is talking about Firefox users as a collective, i.e. “this many Firefox users are searching for animals”. Which is something it’s done for ages, albeit not for what websites people are loading. (But it is known, for example, which menu items are most used.)

    I’ll also note that that post is not about advertising but about what features to develop, but I’ll grant that it’s not a big leap to use it to serve more granular advertisements as well.


  • How to free the rest of the web from advertising is not Mozilla’s problem.

    It kinds is though, the reason it exists is to ensure the internet is a healthy global public resource.

    Some of the many hundreds millions of dollars they’re paid annually in excess of what it costs to maintain a web browser

    AFAIK Mozilla nets about $500 million a year from Google being the default search engine, which is roughly the entire budget, and is lower than what Google and Apple spend to maintain their web browsers. So your numbers seem optimistic to me.

    Trying to collect data about Firefox users in order to better target ads at them

    I haven’t seen that happening, or at least, not “collect” in the sense of “Mozilla has data about Firefox users in order to better target ads at them”. Possibly that the user’s own local device has that data.

    Again, Mozilla has always been an ad-funded operation. But also always without doing surveillance.

    (I do 100% agree that it is a risky business to be in and that I’d hate to see it cross the line, but I’m withholding judgment until I actually see that happening.)
