Favicons alone aren't really enough though. I routinely have multiple tabs open for Wikipedia, Youtube, Arxiv.org, Jira, Reddit, and even HN.
With Firefox, you get the Favicon and at least the first few characters of the page title. And if you use the tab drop-down, you see all, or most, of the title (depending on how long it is).
I don't know what to tell you then. I'm typing this comment right now using Firefox, with a tab-bar full of tabs, and every visible tab has the favicon and a portion of the title visible. The rest can be found in the drop-down, with nearly the entire title displayed.
Maybe there's some setting that controls this behavior, but my Firefox is pretty much completely stock. shrug
Interesting. Maybe we're running different versions, or maybe it's somehow dependent on screen resolution or something. Weird. For me, Firefox has always displayed at least the first few characters of the title.
I was going to say that the favicons on Chrome probably disappear at some point too, but you're right. Chrome guarantees at least half a favicon on display, but to do so, new tabs are not put on the tab-bar. They're completely hidden with no way to access them via the tab-bar.
Yeah, that is not really optimal. However, that is luckily only a problem on a very high number of tabs. Firefox's tab UI starts having usability issues at a much higher number. At my tested width.
