Tab management on Fennec Native, while very good and intuitive, suffers from one minor issue: it's sometimes really difficult to close a tab. The button closing the tab is relatively small, and the thumbnail of the tab next to it is really huge, so many a times, when trying to close a tab, I find myself inadvertently tapping on the thumbnail and going back to the tab that I wanted to close. The issue could be resolved easily if the close tab button was made slightly larger, as well as providing a bit more padding between the close tab button, and the thumbnail of the tab. I am using the latest nightly (14.0a1 2012-03-15) and I have tried this on a Motorola RAZR (Gingerbread, qHD screen) and Galaxy Nexus (Ice Cream Sandwich, 720p screen). I have observed the same behaviour on both phones.
