Get Started

Set Opera as the default browser

You can set Opera as your default browser so that Opera automatically opens when you request any webpages or information from the internet.

For Mac OS X, to set Opera as your default browser, follow these steps:

  1. Open Safari (open “Finder” and look under “Applications”).
  2. In the Safari menu, select Preferences > General.
  3. In the default web browser drop-down, select “Opera”.

Exit actions

You can set certain actions to occur each time you close the browser.

Confirm exit dialog

You can have Opera display a dialog to confirm that you want to exit, to prevent you from accidentally closing the application. To set this, go to Settings > Preferences > Advanced > Browsing and check “Confirm exit”.

Clear cache

To clear your cache every time you exit the browser, go to Opera/Settings > Preferences > Advanced > History and in the Disk cache section, check “Empty on exit”. If you would like a sound associated with exiting the browser, go to Opera/Settings > Preferences > Advanced > Notifications and select “Opera Exit” in the section for enabling program sounds.

Clear cookies

To clear new cookies when you exit the browser, go to Opera/Settings > Preferences > Advanced > Cookies and check “Delete new cookies when exiting Opera”. Cookies created during the session will be deleted, while older cookies will be preserved.

Delete stored documents

To clear any documents stored during your session, especially if you are using a public computer, select Opera/Settings > Preferences > Advanced > History and check “Empty on exit”.

Home page

To set a home page, go to Opera/Settings > Preferences > General and enter the web address in the “Home page” field, or if you’re viewing the webpage in an active tab, select “Use current”.

Add home button

If you prefer to see the home page button on the address bar (or any bar), follow the steps below:

  1. Right-click (or Ctrl-click) the toolbar and select “Customize”.
  2. Select “Appearance”. The toolbar is highlighted by a yellow border.
  3. Select the Buttons tab in the resulting dialog and drag the Home button to the highlighted toolbar.

Import or export data

You can import bookmarks (favorites), mail, feed lists, and contacts from other programs, such as Internet Explorer, Firefox, and older versions of Opera.

To import data:

  1. Select File > Import and export.
  2. Select an import option from the list.
  3. Browse to find the folder that contains your old data.
  4. Highlight and click “Open” to select the folder.
  5. A confirmation dialog appears. Select “OK”.

Importing Mozilla Firefox bookmarks

Mozilla may store the bookmarks file differently to other browsers. If you cannot find the file, try the following steps:

  1. In Firefox, click the Bookmarks button on the right side of the navigation toolbar (Windows XP: click the Bookmarks menu) and select “Show All Bookmarks” to open the Library window.
  2. From the toolbar on the Library window, click “Import and Backup” and choose “Export Bookmarks to HTML”. Save the file in a location you can easily remember.
  3. Follow the steps to import shown above and select this folder for step 3.
  4. The imported bookmarks are stored in a new, separate folder in your Opera Bookmarks manager (Bookmarks > Manage bookmarks).

Export data from Opera

You can export data such as feed lists, bookmarks, and contacts. For bookmarks, if you need to use your Opera bookmarks on a browser on another computer, export the bookmarks as an HTML file (Export bookmarks as HTML). Many browsers can understand bookmarks in this format, even if they don’t understand Opera’s internal bookmark format.

To export data from Opera, follow these steps:

  1. Go to File > Import and export.
  2. Choose the file name, change the location if you want to find it easily, and click “Save”.
  3. Import the data file according to the instructions of your other browser.

Download and install Opera

Download and install the desktop browser

To install the Opera desktop browser, just go to our download page and follow the simple instructions for the latest, official version.

32-bit or 64-bit?

For Mac, the 32-bit build has ceased from Opera 12. We are distributing a Universal Binary containing both 32-bit and 64-bit versions. This means all users on systems that supports 64-bit will use that, or otherwise fallback to 32-bit.

Regular 32-bit and 64-bit versions are available for Windows.

If you want to see what we’re currently working on, have a look at Opera Next.

More than one installation

If you are helping us by testing builds listed on the Opera Desktop Team Blog, you may need to change the installation options. As some of our experimental builds will upgrade your stable Opera by default, it’s a good idea to change the options to install it alongside your stable version instead.

For a second, separate installation, follow these steps:

You can either:


For Mac users:

Opera will read your language settings from the System Preferences on first start-up and automatically apply an appropriate language file and set the preferred content language based on those settings. Please note that Opera is not available in all languages, and most websites may not be able to serve content based on your language setting.

For Windows and Linux users:

To select your preferred language for Opera and for content in webpages, go to Settings > Preferences > General.

If you have downloaded an Opera language file separately, go to the “Details” dialog to apply it. Once you have edited these preferences in Opera, your language settings will no longer be affected by changes to the system preferences.

Language in the website

If you are viewing our website, you can change the language for the site by using the selector at the bottom, left of the screen.

Start up tabs

To select which tabs Opera should open when you launch the browser, go to Opera/Settings > Preferences > General, or by pressing ⌘+F12 or Ctrl+F12.

Opera can start up with the tabs you had open when you last closed the browser, or can start with a previously saved session, or your home page. If you want to choose every time you launch Opera, enable the start-up dialog.
