BitTorrent is a peer-to-peer file-distribution protocol that lets you download large files without putting too much strain on one single server, because the download is distributed. Opera comes with built-in support for the BitTorrent protocol.


Although frequently referred to as “downloading”, the BitTorrent protocol relies on all users to be recipients and distributors of .torrent files. While you download a BitTorrent archive to your computer, you are also helping to distribute it to other users. It is not possible to download without uploading, although you can set restrictions on bandwidth usage.


Note: BitTorrent is enabled by default, but it may be disabled; see Turn BitTorrent off below. For details about disabling this system-wide, see the System Administrator’s Handbook.

Use BitTorrent


To use BitTorrent to download a file:


  1. Click a .torrent link.
  2. In the resulting dialog, specify where you want to downloaded the file. You can also change BitTorrent preferences from this dialog.
  3. Click “Yes” to start downloading.
  4. After some of the file has been downloaded to your computer, you will start sharing the parts you have already received with other BitTorrent users, also known as peers. The more peers that help distribute a file, the faster the download will be. You will continue sharing content even after your download has finished.
  5. To stop sharing, either stop the file transfer, or close Opera.



The first time you use BitTorrent, your operating system or firewall may warn you that it has just blocked Opera. This happens because Opera attempts to open the necessary server port for sharing content, and your firewall just wants to make sure that these ports are not opened without your knowledge. If this happens, just unblock Opera before proceeding.


If you find that BitTorrent does not work for you, see Listen port and testing below.

Turn BitTorrent on


Opera’s built-in client for BitTorrent is enabled by default. If you have disabled it and wish to enable it again, follow the steps below:


  1. Follow this link or copy and paste it in the address field: opera:config#BitTorrent|Enable
  2. Click to add a tick to the checkbox marked “Enable”.
  3. Click the “Save” button. You may need to exit and restart the browser for changes to take effect.

Turn BitTorrent off


To disable Opera’s BitTorrent client, follow the steps below:


  1. Follow this link or copy and paste it in the address field: opera:config#BitTorrent|Enable
  2. Click to remove the tick in the checkbox marked “Enable”.
  3. Click the “Save” button. You may need to exit and restart the browser for changes to take effect.

Using a third-party BitTorrent client


If you do not necessarily want to disable Opera’s BitTorrent client but wish to use a third-party client instead, follow the steps below:


  1. Go to Settings > Preferences > Advanced > Downloads
  2. Click to remove the tick in the checkbox marked “Hide file types opened with Opera”.
  3. Type “torrent” in the search field.
  4. Double-click the line that looks like this:
    application/x-bittorrent torrent


From this dialog, select either:


  • Open with default application — use your system’s default BitTorrent client
  • Open with other application — define a preferred client


Note that this will not actually disable Opera’s BitTorrent client, but it will associate torrent files with your preferred BitTorrent client.

Change BitTorrent preferences


Access BitTorrent preferences from the dialog that is displayed when you start a torrent transfer.


You can specify how much bandwidth to allow for downloading and uploading respectively. For example, if you find that BitTorrent takes up too much of your available network capacity with the default automatic bandwidth restriction, adjust these settings.

Listen port and testing


Your computer may not be set up to share BitTorrent files. To test this, follow the steps below:


  1. In the preferences, use the “Test” button next to the “Incoming listen port” field to check whether your current setup will work.
  2. If the test fails, try the following:
    • Change the port details in the field that specifies which port should be listening for incoming connections.
    • Check whether the ports used for BitTorrent are blocked by your service provider or system administrator.
    • Change the setup of your router and/or firewall to allow incoming BitTorrent connections on the specified port.


When you want to download something from a website, for example a file, a Download dialog appears.

Click “Open” to save the file in the download directory and open it when it has been downloaded. Opera sets up a default download folder for you. If you want a different folder on your computer, click “Choose”.

Click “Save” to specify where to save the file. After the file has been downloaded, open it by double-clicking in the Downloads panel or tab. When using this option, files are downloaded to this directory without asking for confirmation.

Note: Use virus-protection software before executing downloaded files.

Change download preferences

You can decide how Opera should handle files you download by going to Opera/Settings > Preferences > Advanced > Downloads.

The Downloads preference tab lists Opera’s default setup for handling downloaded files. To edit a file type, find it in the list, or type the name in the “Quick find” field, highlight it, and select “Edit”. The table below lists and describes the different editing options in the File type dialog.

Note: Be careful when editing file types. Opera depends on certain file types in order to work properly.

Show download dialog
Display multiple choice dialog on how to handle file.
Open with Opera
Opera can show text, markup languages, and images.
Save to disk
Opera can open downloaded files automatically.
Do not ask for folder, but save directly to
Specify a download location for files of a particular type. Click “Choose” to find a location.
Open with default application
Let your operating system decide which program to use when opening files of this file type.
Open with other application
Use a different application than the one your operating system is set to use by default.
Use plug-in
Use a plug-in to view the file.

Add a file type

To add your own file types, go to Opera/Settings > Preferences > Advanced > Downloads and follow the steps below:

  1. Click “Add”.
  2. Enter the correctly spelled MIME string you wish to set up.
  3. Enter a list of comma-separated file extensions to associate with the file type, for example “jpeg, jpg, jpe“.
  4. Select the action Opera should take when encountering this file type.


Notes can be used for “to do” lists, text snippets from webpages you want to keep around, email message templates, and any other strings of text you want to keep readily at hand.

Tip: Opera Link makes it possible to synchronize the notes on all your computers and all your devices.

Managing notes

Operation How to do it
Write a new note Click “New note”
Create a folder for notes Click drop-down arrow on “New note” button, select “New folder”
Organize notes and folders Use drag and drop
Take notes from a webpage Mark text in page, then press ⌘+Option+C or Ctrl+Alt+C
Search the web for contents in note Drag note to search field and press Enter
Move a note to the trash Click note and press Delete
Retrieve a note from the trash Open trash and drag note out into notes list

Tip: The Ctrl-click menu of all edit fields, such as email messages and webforms, contains the sub-menu “Insert note”. Use notes to store strings of text that you use repeatedly, such as standard email messages or templates, and signatures.

Save passwords

Password Manager is Opera’s password and form manager. Enable it to let Opera store user names and passwords the first time you enter them, and to automatically fill in personal information in webforms.

When you visit a website with a stored user name and password, you can log in simply by clicking the Login button on the address bar, or by pressing Ctrl+Enter.

Note that user names and passwords are encrypted on disk. If you want to protect your Password Manager from other users on the same computer by setting a master password, go to the Security preferences under “Advanced”.

Password Manager passwords can be deleted from Tools > Delete Private Data.

Use master password to protect saved passwords

Note that user names and passwords are encrypted on disk. If you want to protect your Password Manager from other users on the same computer, you can set a master password. Go to Opera/Settings > Preferences > Advanced > Security and check the box marked “Use master password to protect saved passwords”, and then specify how often in the “Ask for password” field above it.


To print a webpage, go to File > Print. You may also be able to Ctrl-click the page and select “Print”.

Print preview

Print preview mode lets you see how a webpage will appear if printed. To switch screen modes, go to File > Print preview. To return to standard viewing, uncheck this option.

Keyboard shortcut: Press +Shift+P or Ctrl+Shift+P.

Print options

You can set print options from File > Print > Options, including:

  • Paper and page orientation
  • Print page background, or headers and footers
  • Fit content to paper width, or scale by a percentage
  • Page margins

Save data for online forms

Some sites require you to fill in personal information such as your name and address. Rather than typing the same information over and over, you can enter it once here.

After entering your personal information in the preferences, you can quickly fill in forms by selecting from a drop-down once you start typing into the field, or by Ctrl-clicking the field.

Ctrl-clicking any input field, including email messages, will produce a sub-menu called “Insert personal”, where you can select information that you have stored in the preferences.

If Opera recognizes a form field as one you have entered information for in the Forms preferences, you can also use the password manager to fill in the field. Click the password manager icon on the address bar or press Ctrl+Enter.

Tip: Use the “Other” fields for alternate addresses or other snippets of personal information you find yourself repeatedly typing into forms.

Save sets of tabs

When you have a set of tabs or windows open in Opera, you can save them as a “session” to use later. This allows you to open all the tabs or windows you had open when you start the browser, or while browsing.

You can have Opera launch with the tabs you had open when you last closed the browser, or go directly to a previously saved session, Speed Dial or your home page. Go to Opera/Settings > Preferences > General and select from the startup drop-down list. If you want to choose every time you launch Opera, enable the start-up dialog. Note that the start-up dialog will always be displayed after Opera has been forced to close or otherwise has quit unexpectedly.

Tip: Try starting with no pages if you have problems starting Opera.

To save a session of tabs or windows to use later on or for a particular purpose, go to Opera > Sessions and name the session to identify it. The next time you want to view this set of tabs or windows, return to this menu option and select the saved session from the list.

Work offline

If you want to catch up on reading webpages and mail while you are not connected, for example, while travelling, or if you want to cut down on internet costs, you can use Opera’s offline mode. Follow the steps below:

  1. Go to Opera > Preferences > Advanced > History and make sure that Cache is “On”, and uncheck “Empty on Exit”. This ensures that the mail and webpages you have open will be available.
  2. Select File > Work Offline.
  3. To return to online mode, select this menu option and uncheck “Work Offline”.

If you are having problems, in the history preferences:

  • Set “Check images” and “Check Documents” to “Never”.
  • Change “Memory cache” to 60mb, and “Disk cache” to 400mb.
  • See settings in the Storage topic.
