Please allow us to still use the more compact mobile tab grid layout we had before this update. Either an option to toggle off the new UI, or adding "Compact Grid" as an option in addition to "List" and "Grid" would be very helpful.
I will also be looking for a new browser if they don't add an option to toggle the tab UI changes off. I hate all the padding, it just wastes valuable screen real estate and makes it take forever to scroll through my tabs
Another vote for this feature - I'd love to permanently switch to Firefox on mobile, but it is significantly less usable than chromium browsers due to lack of tab grouping.
