About Opera

The Opera browser was originally released in 1996 by the Opera Software company. It has remained a popular web browser for many years and is still actively developed today. In 2013, it announced that it would switch from its proprietary Presto engine to the open-source Chromium project.

Opera features a built-in screenshot tool; this is just one of the many features Opera has adopted from other web browsers, including Speed Dial, pop-up blocking, re-opening recently closed pages, private browsing, and tabbed browsing. Opera is a Web browser that is smaller in size, faster and more stable than Mozilla or Microsoft browsers.

Opera has released a new cryptocurrency wallet for Android phones. The app, available on the beta and developer versions of Opera for Android, supports Web 3, which is specifically for mobile payments and cryptocurrency payments. The wallet is highly secure, and funds are stored with full control from the user. There is no need to enter a PIN code or password, as the user's smartphone will act as their way to unlock the wallet.

Opera lets you easily chat through Facebook Messenger, VKontakte and WhatsApp from your PC, including muting your notifications and tracking them on your phone.
