Thumbnails tabs visuall view more then 6
using the CTRL+TAB to show open thumbnails tabs visually is a great feature firefox have over other browsers and what encouraged me to leave chrome. have only 6 inst very effective - this needs to be dynamic (for at least 10-15 tabs) and going over the web is seems a lot of people asked this feature.
Is there a way to change this? if not where can I ask a feature request?
