If the icon file you select is valid, the icon is displayed immediately. If the icon file you select is invalid,
the standard Opera icon is reinstated.
Operation
This is where you can make changes regarding the usage of Opera.
Under Autocomplete for web addresses you can specify that addresses will be automatically
completed in the address bar, i.e. Internet addresses appear automatically in the address bar after you
have entered the first few letters of the address. If, for example, you enter just one word only, then top-
level domain suffixes like ".net" and ".com" are added to the end and the prefix "www." to the beginning.
completes. Disabling this function can speed up Opera a little.
Under Show source code you can specify whether, when Show source code is selected in the
website context menu, the internal editor in Opera should be used or another program, e.g. Windows
editor (notepad.exe).
Performance
You can turn on fast navigation again here, which is set to automatic mode by default in Opera 9
onwards.
By selecting Automatic mode, you can specify that the web server setting should be taken into
account when you navigate through the browser history, which informs the browser whether a site can
be loaded from the cache using "Back" or "Forward" or whether the website should be downloaded
anew each time. The latter is necessary for certain shop pages to function correctly. However the server
often demands that the page be downloaded again from the web server when it is not necessary.
By selecting Compatibility mode you can specify that, regardless of how the server is set, the sites
are never downloaded from the browser cache when you navigate through the browser history, but are
always downloaded anew from the website. This setting is generally not required and is not
recommended for fast surfing.
By selecting Fast mode, you can specify that the websites already on your computer are always
loaded from the cache. This not only has the advantage that the back and forward functions are
suddenly very fast again, but also that a lower data volume needs to be downloaded over the Internet
connection. Furthermore, entries you have made into form fields are generally retained during navigation
in a browser. For websites to function correctly with active site contents, it may however be necessary
to manually refresh the websites regularly (e.g. using F5).
Search
Here you can set which search engine Opera should use in general and for speed dial and how the
speed dial should be displayed.
Under Default search engine you can specify which search engine Opera uses. This is automatically
selected in the search field, in the address bar, when "Search" is selected in the context menu of
selected text and when entering several words in the address bar.
Under Speed dial default search engine you can change the search engine that is displayed by
default in the speed dial page in a new empty tab.
