How to disable Opera Error console easily
Stumble it!
Opera error console is very disturbing for all the Opera users. It just pops up and interrupts whatever you are doing and yes, it is very annoying. Most of the people using Opera and are confronting this stupid error console. But, there’s a very easy way to disable Opera Error Console.
Earlier, there was a small tweak file known as Opera Error Console killer but it wasn’t up to the mark either! So here’s something that actually disables the whole Opera error console crap.
1. Open Opera (and see the error console lol)
2. Goto tools and click mail and chat accounts. You will see a account there (your mail account), select it and click on Edit.
3. Next, you will see a “Incoming” tab there, select it and click the account properties dialog.
Un-check or Disable the setting called “Check for new messages every 5(default) minutes”
And you’re done! Restart Opera and you won’t see any error console. This usually happens when you have inactive mail account & on default Opera checks emails after every 5 minutes and regarding to that, it pops up the Opera Error console.
Now there is another possibility that the Opera error console has been set to show the errors it sees on the websites. To prevent that from happening, do this small thing.
Enter opera:config#Error Console Filter in the website address bar, click default and the click the save button. It will do the trick 
Happy Browsing
whoaaa! this is really helpful! i like opera because it has a notepad in the browser but this annoying error console made me crazy that i used a different mail client. now im back to opera thanks to you!
If you know of a way that actually works to turn off the Error Console, I’d love to hear about it. You solution has zero effect. That selection was unchecked already. Maybe there is some magic in the “account properties dialog” that I do not have. I’m using Opera 9.64
Just one of many things that make this browser unusable. Too bad. Some good work going down the ….
