So I found this wonderful archived thread https://support.mozilla.org/en-US/questions/1260799 that helped me add microsoft 365's website to a blocklist json, which is great, since microsoft apparently decided it was going to start opening the site after I uninstalled microsoft 365 (go figure). So from here, I am wondering if there is a way to automate closing the tab after the site is blocked? Am I approaching this from the wrong angle maybe? Any advice appreciated! I just really don't like microsoft thinking it can open tabs on it's own to advertise a thing I clearly don't want. PS if I am posting in the wrong topic, I apologize.
