Opera Mini Secret Codes

Opera Mini Source Code Display

Opera Mini has some special commands that you enter in the address bar like a URL but without the “http://”. Many of them return information that’s probably only of interest to Opera’s developers but a couple are actually very useful.

My favorite is config: which opens Opera Mini’s Power User Settings page where you can tweak  many browser settings like the timeout and whether the browser should make phone numbers clickable. See my post Opera Mini’s Hidden Power User Menu for more information.

Web developers will appreciate server:source which displays the source code of the current page.

Here’s a full list of all the hidden Opera Minicommands that I’ve discovered. I’ve tested these in Opera Mini 4.3 and 6 and I believe that (except as noted) they should work in all Opera Mini versions since 4.0.

config: – Open the the Power User Settings menu
server:source – Display the current page’s source code
opera:cache – displays the size and URL of cached pages and images
about: – displays information about the Opera Mini server
debug: – Displays a page listing many Opera mini server and client properties. The “Host:” field tells you which Opera Mini server you are currently connected to.

The first letter of the host is supposed to indicate which country the server is in.  I believe that “r” hosts like “r02-12” are in the US. as I’m in the US and I’m usually connected to “r” hosts. I’ve also seen or heard of “t”, “z” and “v” hosts. Anyone seen others or know where any of them are?

The following commands duplicate Opera Mini menu functions.

feed://list – Go to the Feeds page
opera:about – Displays copyright and license information for third party software used in the browser
server:reset – clears all cookies
server:refresh – refreshes the current page
o:A – goes to the start page (Opera Mini 4.n only)
o:Z – goes to your bookmarks (Opera Mini 4.n only)

I suspect that there are more of these hidden commands. If you’ve discovered others that are currently working, please lets all know in a comment.

  1. There are more commands that can be used in opera mini, such as:

    ‘about:about’ and ‘debug:console’ .
    ‘debug:console’ is very useful for js programmers as the errors and console.log’d values go here.

  2. could you tell me how to set complex script in opera mobile browser. I know how to set it in opera mini browser but it is not there in opera mobile browser pls help.

  3. How can i recover my saved page in my operamini 4, i did not know i deleted it. please can you reply me here, i dont login with my email always

  4. I cannot log on easily. Always it is ‘connection failed. What is the problem?.

    • feed:list worked in 2011 when this post was written. It looks like Opera has changed it so now you need to use feed://list

      I wonder why they did this? Changing long standing pseudo-urls is not very user friendly.

  5. When i try 4 facebook from opera mini ,it always shows an error message ‘ Remote server or file not found’. moreovere, i have been using facebook for 2 months with opera mini.

    • Do other sites work with Opera Mini? If not reinstall it
      Does Facebook work with UC Browser or the phone’s built in browser? If they don’t your operator or government might be blocking Facebook.
      Also try alternate urls; m.facebook.com, facebook.com, 0.facebook.com, http://www.facebook.com
