Opera’s Internal Opera is a series of articles that will explore the company’s internal culture and how it affects the way opera is performed. This series will also cover topics such as how opera is created, how it is interpreted, and how it can be used to promote social justice. The Internal Opera series began in October of 2017 and will continue until May of 2018. The goal of this series was to provide an understanding of Opera’s Internal Opera and what makes it so special. In this first article, we discuss the history of Opera and how it has been used for social justice. Opera was created in 1812 by Giuseppe Verdi and his friend Luigi Pirandello. It was originally meant to be a vehicle for political protest against Napoleon Bonaparte. However, after Napoleon’s defeat, Verdi decided to keep Opera alive as a way to express his feelings. He continued writing operas until his death in 1865. Today, Opera still uses its political messages to promote social justice. For example, Aida is one of the most popular operas ever written and has been used as a platform for protesting dictatorships around the world. The opera has also been used as a way to raise awareness about human rights issues. In fact, Aida has even been banned in some countries because of its content! Despite its protests against dictatorships, however, Opera still uses its music to entertain audiences around the world. In fact, many people believe that Opera is one of the most important forms of art in society! It can help people connect with each other and learn about different cultures while providing entertainment value!


Opera contains hidden features that aren’t exposed in its user interface. They’re on internal pages, which you can access by typing Opera: into the address bar, followed by the name of the page.

Opera’s hidden Opera: pages are its counterpart to Firefox’s About: pages and Chrome’s Chrome:// URLs. They contain hidden options, alternate user interfaces and diagnostic information tucked away from the main interface.

Exploring the Opera: Pages

Opera doesn’t have an internal page that lists all its internal pages, like Firefox’s about:about and Chrome’s chrome://about pages do. If you want to view a list and explore them yourself, you can install the Opera Internal Pages extension. It adds a toolbar button that lists all the pages.

You can access some of these pages from the standard Opera menu. For example, the opera:about and opera:help pages are the same as the About and Help options in the menu.

Opera:Config

The opera:config page is Opera’s counterpart to Firefox’s famous about:config page. It contains a wide variety of options and tweaks, many of which aren’t available elsewhere in Opera’s user interface.

The page is completely searchable, so you can quickly find the option you’re looking for. Unlike the confusingly named options on Firefox’s about:config page, Opera’s Preferences Editor page contains options written in plain English.

Opera:Plugins

The opera:plugins page displays a list of your installed browser plug-ins. You can click the Disable option to disable a plug-in without uninstalling it entirely.

The “Enable Plug-ins” check box controls whether plug-in support is enabled browser-wide. It’s the same option you’ll find in Opera’s Quick Preferences menu.

Opera:History & Opera:HistorySearch

The opera:history page displays a different view of your history — it’s not the same as the History option in Opera’s menu.

The opera:historysearch page allows you to search your browsing history. Like the search option built into Opera’s standard History page, it offers full-text search of pages.

Opera:Cache

The opera:cache page allows you to browse Opera’s browser cache, which caches downloaded content to speed up future load times.

Select a specific website to view its cached files or save them to your computer.

Opera:Debug

The opera:debug page allows connections to remote Opera Dragonfly sessions. You can use this feature to debug remote Opera systems over the network.

To connect to another browser from this page, the other Opera user must launch Opera’s Dragonfly developer tool (Opera -> Page -> Developer Tools -> Opera Dragonfly) and enable remote debugging.

Opera:Drives

The opera:drives page lets you browse your local file system from a web-page-style interface within Opera.

Opera:MemDebug, Opera:WebStorage and Opera:WebDatabases

The opera:memdebug page breaks down Opera’s memory usage. The opera:webstorage and opera:webdatabases pages list websites using Opera’s Web storage and Web database features.

Opera’s internal Opera: URLs don’t contain fun Easter eggs like Firefox’s or experimental  features like Chrome’s, but there are a treasure trove of hidden options for you to explore — particularly on the opera:config page.
