Perhaps even more impressive, Opera 11 is actually 30 percent smaller than previous releases, saving you a bit of download time and disk space. The speed boost is particularly noticeable on Linux, where Opera 11 is roughly 30 percent faster. Opera hasn't given any hard and fast numbers, but in our experience Opera 11 is faster than its predecessors and on par with Firefox 4b7 and Chrome 8. Of course, all the new features would be less exciting if they slowed things down, but luckily they don't. It's more elegant, and it plays on a behavior many users – those with iPhones or iPads – are already familiar with.

However, Firefox 4's current implementation (still in beta) suddenly looks awkward and primitive next to Opera's take on the same idea. To access the tabs in a stack, you simply mouse over the group and it expands, or you can click the arrow to the right of the grouped tab, which has the same effect.įirefox 4 will also introduce a new interface for grouping tabs when it is finalized in a few months.

Your 'stack' then collapses down into a single tab. You group related tabs by dragging them on top of each other. Tab Stacking is ingeniously simple and works a little bit like the way you create folders of apps on the iPhone's home screen. Opera 11 introduces 'Tab Stacking,' a way to group your tabs together to better organize the webpages you're viewing. Opera may be the last browser to get extensions, but it's still leading the pack when it comes to innovative ideas for tabbed browsing. There, you'll see a new option to only load plug-ins on demand. Just head to the preferences menu, select the Advanced tab and then click Content. Opera 11 can now be set to load plug-ins (like Flash or Silverlight) only on demand. Actually you probably will, but you don't need them. One thing you may not find in the new extensions store are Flash-blocking add-ons.
