At the end of the day, you have to trust someone and a few black boxes in between as soon as you connect to the internet. So if there’s something I’d really rather not let out into the world, it’s either on an airgapped encrypted system or a piece of paper hidden where my keys get lost.



Love the summary format. Definitely a lot more accurate of a fingerprint using Chromium, many stats with Librewolf are jumbled up as expected. In fact, all is well in Chromium.

It commented on Firefox RFP reporting UTC regardless of local time zone and I thought it was funny that I do in fact have my devices set to UTC even though I don’t live in Iceland. To be clear, not a bug, just my personal choice.
