We're rolling out Opera 17 for desktop today. To double-check if your Opera is updated, go to About Opera and see the Version information – it should now reflect Version 17.0.1241.45.
You can also download Opera 17 here.
In Startup settings, you can now choose to:
– Continue where I left off
– Opera the Start Page
– Open a specific page or set of pages (Set Pages)
Opera starts with your last session by default, but we're giving you the option to start with the above choices.
Opera 17 comes with Pinned tabs. Never accidentally lose your important tabs again.
You can now customize your searches. Change the keyword to each customized search engine to one-letter shortcuts to search faster. You can use "d" for DuckDuckGo, for example. Searching via DuckDuckGo would then only require you to type "d and your search words" in the combined URL and search bar.
