My MyPal68 buttons are uMatrix green, uBlock origin red, User-Agent Switcher pink, change geolocation green, SuperStop white, Forget Button blue.
User-Agent Switcher gives me one click access to change UA's, I've added some custom ones to the bottom of the list, and what I really like is it'll save the UA per website and auto-switch for you.
What I really want to point out is some websites I've still had trouble after switching to W10 / FF119, but when I switch to identify as Linux11 / FF83 some of those trouble websites start working! Clearly they are more lenient to serve different Linux systems without demanding the latest-and-greatest, compared to the IronFist approach to Windows systems.
