At my current browser width, I can fit about eight or nine tabs across the top before they start disappearing off the right. There is a small UI widget to indicate you can scroll to the "hidden" tabs, but it's not entirely obvious if you don't go looking for it. If I already have my 9 tabs open, a tenth one won't seem to do anything as I don't see the tab and may not notice the new widet.
Personally I default to opening links in the same window I'm in. If I want it in another tab or in a new window I right-click it. In cases where I do that it doesn't matter whether you've targetted the link or not. In cases where I just click it, I'm not terribly bothered by the new window if it appears. (Now that I'm using a tabbed browser, that is.) But for people with other defaults, I can understand it conflicting with their preferred settings.
