Opera 11 beta released

Tabbed browsing – one of the essential features in all browsers – has evolved yet again thanks to one of its pioneers.

Traditionally, tabs were opened side-by-side, but now people using Opera can stack their tabs, grouping them by site or by theme. Opera says that tab stacking reduces clutter and makes it easier to identify and work with sets of open tabs.

To stack tabs one simply drags one tab on top of another. Hovering the mouse over a tab will cause the stack to expand in a visual preview. Clicking the arrow icon expands the current stack across the tab bar. This brief video showcases tab stacking in action.

“Tabs are the most popular feature in browsers today,” said Jan Standal, VP of Desktop Products, Opera. “Because so many of us wrestle with tens or even hundreds of open tabs, we needed a way to simplify tab management. Just like stacking papers for future reference, stacking your tabs is an intuitive way to organize and collect your open Web pages.”

Extensions go to 11

Since the introduction of extensions in the Opera 11 alpha, Opera reports that more than 500,000 extensions have been downloaded and between 10 and 20 new extensions are uploaded each day. The full extension catalog is available here: https://addons.labs.opera.com/.

Opera has announced a new developer mode in Opera 11 beta, which promises to make extensions easier to develop. Developers can use the developer mode to launch, test and package extensions quickly, Opera says.

Mouse gestures go to 11

“Since their introduction in Opera 5, mouse gestures have proven to be one of the most loved Opera features,” Opera says.

Mouse gestures provide a way to control Opera by moving the mouse in particular patterns.

In Opera 11, a new visual interface highlights mouse paths and helps guide the discovery, use and mastery of these shortcuts. The full list of mouse gestures is available here: http://www.opera.com/browser/tutorials/gestures/.

But wait! There’s more

Opera has also announced the following features in Opera 11:

  1. The address field now hides unnecessary information and puts the security status of each page front and center. Badges explain the security state of the site, aiming to give the user clear information about the sites they visit.
  2. Plug-ins can be set to load on-demand. Opera claims that this can give as much as 30 percent performance improvement.
  3. Extensions and Opera Unite applications are updated automatically through Opera’s update mechanism.
  4. Opera says that more work has been done to boost browsing speed, particularly for Linux. Opera 11 for Linux is 15 to 20 percent faster on common benchmarks than Opera 10.63.
  5. The new bookmarks bar replaces Opera’s personal bar.
  6. Opera 11 is 30 percent smaller than Opera 10.63, despite including new features.
