Beyond what customization you can do to the browser any changes beyond that is either a userChrome.css or 3rd party software to do that.

Normal tabs usually have a minimum width of 76 pixels, which you can reduce to 50 in about:config. Both should leave space next to the mute/unmute icon to click the tab. Example screenshot comparison attached.

Are those pinned tabs? Pinned tabs show the icon only (Pinned Tabs - keep favorite websites open and just a click away).

Or are you using userChrome.css rules to narrow your tabs beyond the available settings? In that case, check with your rules provider on whether they have code available for this that works with the code you already use.

Why is this not just an option in settings? This is why a lot of people leave FF. Definitely not user friendly when people have to go to dev mode to do simple things like this.
