First of all, I would like to thank you for your excellent work, dear Firefox team!
In my everyday life I have a lot (about 50-100) open Firefox tabs. I have to switch back and forth between these tabs regularly. However, this switching becomes torture because the arrow symbols provided for this purpose do not allow me to switch quickly (if I want to switch from tab 1 to tab 50) or slowly (if I want to switch from tab 55 to tab 60). With the arrows it goes very slowly at first and then the change suddenly races off. You can't really dose the speed of the tab change very well. A tabulator scrollbar could help here. Maybe you guys have a better idea... but as it is now, it's very impractical for me. Thank you! 🙂
