Few things left to imprive Rated 4 out of 5 stars
Idea is good, but still buggy.I'm using Firefox Panorama everyday, to group few sites, it is like opening 3-4 Firefoxes in the same time, but with lesser memory usage, and lesser space needed.You shouldn't let Tile View to open tabs from different groups in panorama automatically. I mean when I click accidentally on the icon, but only 1 tab is open in the group, it automatically opens +1 tab from another group. When only 1 tab is open, it should open a BLANK page, or google, or anything else, but please do NOT mess up the panorama groups. In this way it is very hard and confusing, to make it like it was before.
+1) Not using Tile View 24/7, only when I need 2 tabs in the same time. And it can be really annoying, when trying to turn OFF (close layout), by clicking on the toolbar icon, and the icon became inactive, but when I restart FF, it opens it again, and I have to press F12 (or close layout) to turn it off again. It would be a cleaner, and better way to CLOSE layout on clicking on the icon. Since I can reopen tileview with 1 click on icon after closing...why not?
