Just starting to use the Beta Logitech Options+. Here is first piece of feedback
I;ve added Firefox as an app for my MX Master 3 mouse to use.
COnfigured the middle button to be close window. That works well. Changing the horizontal scrololl whell to navigate between tabs does not work. It sort of randomly flickers on usually the first and last tab but is not controllable in any way. This same setting works as expected in Chrome
