Tabs just take up valuable space when you're looking at page contents. Probably self-hiding tabs that explode out of the left edge of the window under some provocation would be best. That would allow lots more room for page titles in the tabs. (East Asian users might prefer they explode from the top edge instead; southwest Asians might prefer the right edge.)
As it is, those of us who keep a gross or more of tabs open at once, distributed among dozens of windows, (I do not kid) don't get to see much of page titles in the tabs.
