I just got in the habit of turning it off, when I'm either too lazy to bother, or I'm on a site I'll probably never visit again. sites that are already setup ofc generally stay that way.

The big headache is when you have a site half-setup -- its correct for all of your usage, and then you try something new and you get a video that doesn't load, and you sit there waiting until you realize umatrix probably found something new
