Fine-tune Opera's handling of webpages.

Press Page Down and Page Up to switch slides

Page loading

Under "Loading", set your preference for how soon Opera should attempt to display a page after it starts loading.

Page icons

A webpage can specify a small icon to represent itself. Opera will display this icon on tabs and bookmarks.

The standard method of doing this is to specify link rel="shortcut icon" in the page document. However, on some servers a file called favicon.ico is put in the root directory without a link from the document.

By default, Opera will display both types of icons. You may also choose to ignore both types of icons, or to display only icons correctly linked from within documents.


The scroll bar is normally placed on the right side of the screen, indicating the length of the current document and your current position within it. You may scroll the document by clicking on the arrows in either end of the scroll bar, or by dragging the indicator with your mouse. If you prefer not to see the scroll bar, uncheck this option.

If you scroll using a mouse wheel or the arrow keys, would you like Opera to jump directly to the point in the document you are scrolling to, or do you prefer seeing the document scroll smoothly into position? Enable smooth scrolling if you prefer the latter.

Page size and tooltips

The title bar is the bar at the very top of the Opera application window, which displays the title of your currently active webpage as well as Opera [version number].

Check the "Show webpage size in title bar" setting if you would like the title bar to display the current size of the active webpage before this information — for example if you have made a webpage and want to know how it looks with different window sizes.

When you hover certain elements in Opera or on webpages with your mouse, Opera displays small tooltips that add information about the element. If you do not want to see them, uncheck the "Show tooltips" option.

You can also have Opera display a dialog to confirm that you want to exit, to prevent you from accidentally closing the application.

Window menu

Opt to display the Window menu on the main menu bar if you want options for resizing, rearranging, and closing tabs and windows to be available from the menu.

Spell checker

The spell checker checks your spelling within any multiple-line text input field: when filling in forms, composing an Opera Mail message, typing notes, or chatting. Spelling errors are identified by a dotted red line under the word. For single line text fields, spell checking is not automatic, but you can activate it by right-clicking (or Ctrl-clicking) in the field to display a context menu and checking "Check spelling".

Fixing spelling errors

To view suggestions for correct spelling, right-click (or Ctrl-click) a misspelled word to display a context menu, and then select the word with the correct spelling. You can also add the word to your default dictionary, ignore all instances of the word, or remove the word from the dictionary.

Adding a dictionary

Opera uses the Hunspell dictionary format, and includes a US English dictionary by default. To add a spell checker dictionary for another language:

  1. Right-click (or Ctrl-click) in an input field to display the context menu.
  2. Select Dictionaries > Add/Remove Dictionaries.
  3. In the Spell Checker Dictionaries dialog, select the language. You can use the Quick Find field at the top of the list to quickly search the full list.
  4. Check the language you want to use and click "Next".
  5. Read and accept the license, and click "Next".
  6. Choose the default dictionary and click "Finish".
