[Tutorial] How To Use Opera Browser Hidden Functions

Opera has many hidden features that are not available from the browser interface, but displayed in external links. Opera does not have a page that lists the different pages available internally as we can find in Firefox with about:about or Chrome with chrome://about. So you will have to manually enter the address of each internal page to access its contents and in this tutorial I will show you some examples.

To get started open your Opera browser and use below commands to get started.


Page opera:config allows you to access to many Opera settings. In here you can refine some options that do not appear in the Opera menus.


Page opera:plugins displays a list of all installed plugins. You can disable a plugin by clicking the link Disable next to plugin name.


Page opera:history shows a view of your browsing history different from the one you can find in the browser menu. Visited pages are sorted by day and by hour.

Page opera:historysearch lets you search your browsing history.


Page opera:cache lets you browse your browsing cache that contains the elements of web pages you’ve visited, including images, text, style sheets, videos, music, etc..


Page opera:debug lets you connect to another Opera browser on another computer to access the browsing session. This can be used to solve a problem.

To connect to another computer from this page

Step 1: Another user must enable the development tool Opera Dragonfly by clicking on the Opera menu -> Developer Tools -> Opera Dragronfly

Step 2: He then must click on the Configuration option for remote debugging. Select the port to use and confirm.

Step 3: For your part, enter the IP address of the machine that contains the Opera as well as to control the port specified by the user and confirm.


Page opera:drives lets you browse your hard drives in a web-like interface


Page opera:memdebug displays information about the Opera memory usage


The pages opera:webstorage provide information about the data stored locally on your computer from web sites you previously visited
