I think Opera needs to disguise itself as a different browser, such as Firefox or Chrome.
This would be needed on websites that are not able to run browsers such as this.

An example being Scratch (scratch.mit.edu)
I tried to run a project, but failed when an error popped up saying that the website did not accept Opera, only Google and other popular browsers.
