the single tab mode breaks some of the pages - regardless of ad-block. the tiling block is no different than popping two browser instances side by side. please consider changing that hideous icon into something less flamboyant.

I like it. I miss so badly this configuration from Zen Browser in vanilla firefox.

This addon can add several tabs into one. Mosaic view sucks, but the Iframes is quite cool. I will give 5 stars when other addons work in the Iframe view, not just for adblock, but for password manager, mouse gestures, etc
