Did my roughly-monthly update of Debian Unstable yesterday, and got yet another new version of Firefox. Quite sobering to see the extra protections being triggered now, on sites that I regularly visit. I got a warning earlier today about fingerprinters on aljazeera.com, though on revisiting the site a minute ago these no longer show up. Still an amazing number of cross-site tracking cookies, also present on arstechnica.com. The report for the latter shows a couple of fingerprinters currently being blocked, even though I got no explicit warning about that. It also says that “cryptominers” are blocked by default, but when I visited a certain well-known torrent-search site which has a policy of mining bitcoins on users’ machines, it didn’t show any present on that site, even though I could still hear my machine’s fans cranking up from the increased CPU load (which went away when I closed that tab).
