For me, this is step backwards, because it breaks existing UI paradigms.<p>Why is it a good thing for the preferences pane have to appear in a different place from where it does in <i>every single other application on my OS</i>?<p>And this deliberately confuses application content versus Internet content. Do you have to scroll down to click "OK"? What if it isn't visible? Or should it be labelled "save"? Why learn a new dialog-style interface? And why on Earth does this need to be a tab -- are people going to be tabbing between their stock quotes, news, and browser Preferences tab?
I like this because the current options window is modal and often I need to change an option while browsing the web.<p>I hope they do the same with the downloads list.
I'd like to see per-tab offline mode, a-la <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=226096" rel="nofollow">https://bugzilla.mozilla.org/show_bug.cgi?id=226096</a>
I really don't care for Firefox's new versioning scheme. I'm still on Firefox 10 on Gentoo, and I don't feel much of a reason to upgrade. I felt that incrementing that number should be reserved for major changes. I didn't intend for this to be taken as a complaint about the Mozilla development team. It's just something I've found unusual in the development community. It's been confusing me, and I never understood their reasoning behind it.
