But not in terms of ui, tabs shrink till they hold no text in chrome instead of scrolling like in firefox.
The firefox tab scroll feature is probably the feature I hate the most, in any browser (yes, you can disable it - but bad defaults stink and you can't just go around and change the settings in everyones browser).
First time I've come across someone that doesn't hate it :o
I remember Firefox used to have the bad behaviour like chrome(back in the 1.5 days) and I would occasionally use an IE shell called crazy browser to do my extremely many tab surfing(I also used 2 browsers partially so I could surf something else while 70+ political blogs or webcomics were loading since browsers tended to freeze for a long time on that back in those days).
I much prefer the Firefox tab scroll feature, compared to Chrome's way of handling tabs. The handy "show all tabs" dropdown is nice as well. Between the two, I find managing large numbers of tabs to be easier and less painful in FF than in Chrome.
YMMV.
