Opera uses a completely different type of tabbed browsing than other browsers like Firefox and Netscape use. Opera uses MDI (Multiple Document Inferface) instead of SDI (Single Document Interface). This means that all your windows are handled inside opera. For example, say your browsing in Firefox and you click a link that is meant to open it a new page, it will open up a completely different window with a new set of tabs. In opera, it will open in a new tab, everytime. Even if you have popup blocking disabled, even popups will open inside opera, not in the taskbar, unlike in other browsers where they open in completely new windows.
What are the other advantages to MDI? You can view more than one tab at once, all inside opera! The attachment show examples of opera tiling windows. To tile windows press F6 + shift, press F5 + shift to cascade. You can also use find the cascade and tile buttons in tools-appearance-buttons-browser. This really comes in handly when you need to view more than one page at once.
(Tip: When cascading or tiling, you are likely to get a horizontal scrollbar, use fit to window width to make it go away by pressing ctrl + F11 or going to view>fit to window width.)
