Holy crap, I cannot describe how useful this is. You are amazing. One handed operation is great, but if anyone else noticed—there's no forward button! Like no functionality for one in system UI OR Firefox! Luckily, our dev hero saves the day and many minutes of accidentally swiping to some random assigned action while navigating Firefox, and subsequently raging. Seriously utubo, thank you so much. <3

(sidenote: there are customizable simple gestures for opening a custom url, closing or opening a new tab, reloading, etc! imo should be implemented in every android os natively.)
