New Simplified User-Agent String of Opera Browser

Opera Software today released another major stable build for desktop platforms, Opera 12.10, which brings many new and exciting features. With this release, Opera has also changed its default User-Agent string to a simplified version. Opera has dropped the “U;” token and language indicator, similar to other major browsers like Mozilla Firefox and Google Chrome. This change had appeared in the Opera 12.50 ‘Marlin’ snapshot build released in August this year.

Here are the older and newer User-Agent strings of Opera on Windows 8

Older UA (Opera 12.02)

Opera/9.80 (Windows NT 6.2; U; en) Presto/2.10.289 Version/12.02

Newer UA (Opera 12.10)

Opera/9.80 (Windows NT 6.2) Presto/2.12.388 Version/12.10


Just to remind you here, Opera recently introduced an option to allow users to set their own custom UA string. Using this option, users can specify their own user agent strings apart from the popular ones. Opera already has settings to identify & mask as other browsers to fight with the browser discrimination.
