Opera's Settings File Explained

This document contains information about Opera's configuration options.

Opera6.ini -- "Opera Preferences" on the Macintosh -- is an initialization file for Opera, essentially a settings file that specifies most of the user preferences. When you alter your preferences within the Opera user interface, this file is automatically modified and saved.

Note: The version number in the file name does not correspond to the version numbers of Opera releases. It denotes the version number of the settings file itself.

This document was last updated for Opera 9.50 Beta.

opera:config

Opera also has an integrated Web page for configuring opera6.ini settings, available by going to opera:config. Here you will find all settings from opera6.ini that are editable manually. Do note that some settings require a restart of Opera.

The list below will link directly to opera:config settings when available. Links will not work in browsers other than Opera 9.

Locations

The opera6.ini file may also be edited directly. This should never be done while Opera is running. We recommend that the customized version of opera6.ini be stored in the Opera directory, which is the first place Opera will look for a settings file. This is particularly important to note if you want to run several versions of Opera with different settings, or you have multiple sets of different settings for the same version.

As a default, opera6.ini will be placed in the user directory (~/.opera on Linux, /profile or a sub-directory of /user settings on Windows). For information on how to used system fixed settings files, please refer to the System Administrator's Handbook. In Opera for Macintosh, the file is called "Opera Preferences".

Tip: The easiest way to see where opera6.ini and other Opera files are located on your computer, is to go to Help > About Opera.

Advice on editing

Make a backup of your original opera6.ini before editing.
Be careful. Do not change a setting if you are not familiar with what it does.
If you end up having to delete your settings file, a new one will be generated when you start Opera, but all previous settings will then be gone.

Syntax and values

For integer fields:

Value = 1 = TRUE; switched on
Value = 0 = FALSE; switched off

Note that some settings are stated in the negative, so that setting to 1 means disabling.
