Making Opera your default browser under Windows, Mac OS X and Linux
Windows
The second time you run Opera, it will start displaying a dialog asking if you want Opera to be your default browser. Even if you have previously canceled this dialog, you can change the setting by doing the following:
- Go to Tools → Preferences → Advanced → Programs
- Tick the checkbox for "Check if Opera is default browser on startup".
- Next time you start Opera, answer "Yes" when the dialog asks you if you want Opera to be the default browser on your computer.
Mac OS X
You can set Opera as your default browser on your Macintosh by doing the following:
- Open Safari.
- In the Safari menu, select Preferences → General.
- Under "Default Web Browser", select Opera.
Note: On Mac OS X 10.2, you can also select a default browser using System Preferences → Internet → Web → Default Web Browser.
Linux
For the two major desktop environments, the easiest ways of changing the default system Web browser to Opera are:
Gnome
- In Gnome's System menu, select Preferences → Preferred Applications
- On the Web browser tab, replace the name of the current default browser with Opera.
- Be sure to leave the " %s" in the browser name field for Opera to be able to launch files passed by other applications directly.
KDE
- Open KDE's control center.
-
Go to
File →Associations - Add Opera as default application for the file types you want to launch directly in the browser, for example text/html.
