And why do I need two links for usb stick?

I looked at a few (3?) monkey extensions (including violentmokey). I don’t remember the details but I think there were issues with all of them (probably privacy issues).

Yeah. I try to keep the number of regular extensions low for security and privacy reasons.

I use chromium for some sites since i have written an extension that gives me dark mode for all sites. And firefox demands that all extensions have to be signed.
