I don't want a PLAY MUTE PAUSE not even a CLOSE button. Especially NOT when they have their own internal state for then they choose to appear and disappear.
I don't want to pay attention to them, I don't want to have to look for them, I don't want them getting in my way any more.
If I want to close a tab, I middle click it ! I already have global mute controls, I don't need an extra volume control, I don't have "tabs making unwanted sounds" problem because I have "Go To Sound Tab" addon installed, so I can easily find any tabs that makes sound and mute it correctly, without a extra, unneeded layer of muting (tab muting, versus app muting versus player muting, that is too many muting options, I don't want to use tab muting personnally so I want these buttons out of here !)
I don't want to have to rely on running violentmonkey script engine on top of my already sluggish browser when I barely have 6615 open tabs.
I want to disable the feature at the root, inside firefox, not patch up webpages like dark reader does.
AAAAAaaaaaaaaaaaahhhhhh h!!!!!!
allow me to introduce you to my co-workers that manage the state power grid, who sit in front of a computer for eight hours a day, never knowing what a keyboard shortcut is, or that pressing 'shift+tab' can move your text cursor to the previous field, or, indeed, that the mouse wheel is also a button...
Well bless them, I'm sure they're really good a hand calculating the number of turns transformer need to have when they place an order
Most computer user that I meet also does not know what a middle click is or what it is for or why you would want to do that.
As such we should not design computers based on what they think they need
and interpret that this means "they don't want an option to remove extra tab buttons"
