The Firefox tab bar is naturally more usable than the Chrome tab bar with large numbers of tabs because it scrolls rather than trying to fit them all in the bar. (I sometimes wonder whether squeezing tabs to the point of absurdity was actually a conscious decision by the Chrome developers to limit the number of tabs people can open and thus memory use.) There are a lot of Firefox extensions that add additional tools to manage large numbers of tabs, of which Tree Style Tabs is perhaps the most popular. There are not as many Chrome extensions, since Chrome's UI is not as extensible.
Actually I usually set firefox to squeeze tabs. I love it. As long as the favicon is visible it works fine. Hiding the favicon in small tabs is the real sin of chrome.
I agree. I'm a tab hoarder with hundreds of tabs open in Chrome. I never do that with Firefox's scrolling tabs because I remember where things are based on their place among the other tabs. Firefox doing a min-width on each tab and hiding the rest makes it impossible to find where that other page I looked at 5 minutes ago went.
