Auto-hide vertical tabs & native ad- and tracker blocker in Firefox

[wrb]

- Please (finally) add an option to show and hide the vertical tab bar when hovering over it with the mouse. This is the main reason why many people use forks instead of Firefox.

- Please add a high-quality native ad and tracker blocker so that add-ons are no longer needed.

(Take a quick look at "Water-Fork" to see how well this works; unfortunately, those versions are so outdated that I don't want to use that browser.)

Thank you for your great work 🙂
