Ok, this is one of the best trick I have tried out personally. Remember last time I mentioned about Adblock+ for opera? The requirement was to add the list manually one by one which was indeed time consuming. And a comment by the reader made me to figure out this new method that will permanently block advertisement in Opera browser.
Blocking ads in Opera Browser
I will make this guide simple for all of you. I got a list from the Fanboy adblock plugin which contains all advertisement urls. So we will tweak the opera urlfilter.ini file that will block all ads, banners from the webpage.
Step 1: Download utlfilter.ini. I have uploaded the urlfilter.ini file onto my server and zipped it in .zip extension. Download and extract it using winzip or winrar program.
Step 2: Open the folder & copy urlfilter.ini file –> now navigate to Opera installed directory which is usually located
- For Windows XP: C:Documents and SettingsusernameApplication DataOperaOpera
- For Windows Vista/7: C:UsersusernameAppDataRoamingOperaOperaprofile
- For Linux: ~/.opera/
- For Mac OSX: /Users/username/Library/Preferences/Opera Preferences/
Replace username with your system username (Ex: John..or navigate to that folder). Now paste this urlfilter.ini in the folder which will replace the old urlfilter.ini file (You can take a backup incase if you’re not sure on how this works). Also make sure Opera browser is closed during this process.
Step 3: Once you’ve replaced the file, open Opera 10 browser and 
Congrats on making Opera an Ad-Free browser!

My folder didn't have a file named “utlfilter.ini”, yet it worked! Thanks!
THX, It Works.
Just be sure to Place it IN the folder and NOT Extract it to the said address (it should Ask about Replacing it with the same but a lot smaller file).
