I designed a "kiosk" for work, that opens multiple tabs automatically and rotates through them. Sometimes the browser will automatically open a tab that goes to mozilla.org, which is frustrating, since it messes with the automatic rotation that I've designed for the kiosk. For example, the latest one opens to "The Tech Talk" article. As much as I don't mind those opening on my personal machine, how can I disable them for this machine? I can't use command line arguments, it has to be done through configuration / extension. I've already disabled all of the session restoring features, among a few other things, that way it can be as simple as possible, without involving human interaction at all. The machine doesn't even have a mouse or keyboard, as we remote into it to work on it. Firefox 105.0.1 64-Bits. MacOS 12.4
