With this release of Opera 66 we are including some updates which will improve and speed up your browsing, along with continued design improvements for your sidebar. The first feature we would like to highlight comes in handy to those of us who tend to close tabs accidentally and later regret it. We have an easy solution for this, one that doesn’t require going to the full history section. When you click the clock icon that takes you to history, your browser will ask if you would like to reopen your recently closed tabs. If you click yes, they will come back as if you had never closed them in the first place.
