It's not a typo. It's also not a particular machine. It's all of my machines.

It's why I stopped using Firefox. It wasn't always like that -- pre-quantum, Firefox was reasonably performant. And post-quantum it was as well (although I never saw the performance gains others reported). I don't remember which release this started happening in, but it was a couple of years ago.

Just to forestall advice -- every time I've mentioned this, people have engaged with me to make sure it's not the usual issues (have I completely erased FF and installed it fresh, am I using extensions, etc.). And many think I'm lying.

But this is my actual experience with Firefox. I was willing to stick with using it on principle despite the fact that post-quantum firefox does a poor job if meeting my browser needs, but I couldn't. It's essentially unusable for me.
