The Opera browser used to be a Java-based web browser in the early days on Symbian phones (opera mini) and windows older versions (XP and prior). Over the period, they’ve evolved in using the latest web technology, but the popularity rate has dropped significantly. However, the newest version of the opera browser is actively developed, giving a tough time to low, competitive browsers like Maxthon, Brave, and Firefox. It can be considered the best browser for Windows 10.
The browser is based on firefox source code/blink-engine and chromium-based source code; hence the browser provides decent speed and HTML rendering. Though Opera originally planned the browser to support smartphones, its UI has the left bar with all the web apps.
Opera supports both Chrome extensions and Firefox add-ons due to its build nature. It comes pre-installed with Adblocking, Website Tracking, and VPN support in private mode.
Just like other popular browsers, even Opera supports cross-device sync with the opera account sign-in. Apart from the Windows OS, the browser is also available for macOS, Linux, Android, iOS, and essential featured phone devices.
