Wait, the for-profit not-for-profit privacy champion funded by half-a-billion dollars a year from Google is doing this? Do you think their then-head of public policy was actually telling the truth when she told me “we’re just another Silicon Valley tech company?” No, couldn’t possibly be. I’m sure there are some benefits of the doubt we could still dust off and send their way.

After fixing two AUR `PKGBUILD` files and a bit of patching, the initial rough Arch repo is online. Even made the package list look good with some fancy indexing. The compile takes a long time, but since it's in a VM I'm not too bothered about it. I will probably make an actual build system, but for now the crontab will suffice.

Firefox has added something new. Something useful. Something I really wanted. Split view.
So, instead of having to open two instances of Firefox and awkwardly arranging them side by side I can just open two pages in the same tab.
I don't know how long it has been since Firefox has made me this happy. The turning off AI button was progress but it was a problem they themselves had created.

Anyone who uses Firefox nowadays does so as an act of rebellion against the Evil Corp, meaning they usually know what they're doing and why. However, Firefox is heading in a different direction and isn't listening to its user community.
