I first encountered tabbed browsing on Opera, and the other browsers later copied. I think it was actually cheaper in terms of resources than another window.

I first encountered tabbed browsing on Opera, and the other browsers later copied. I think it was actually cheaper in terms of resources than another window. So tabs are a hack, that caught on because Window managers on many OSs are so poor. And bookmark UI is so bad, that people prefer tabs. But if you use multiple browsers and multiple tabs, you can easily get discombobulated. I say that, but I can probably cope with about 10 tabs in each, if groups of tabs are related. I like the idea of a freeze tab/site for later. Like when you shop or are filling in forms. But I'd love to see a better bookmark/history UI - and even have that embedded a bit more into the desktop.
