Opera inside FF Rated 4 out of 5 stars

Hi, your extension is very well I like it, but, why with IETab you can have IE inside FF in a Tab and with OperaView not? Only because of license?
A license violation would not only be when a user has Opera inside FF?

Can you not add a disabled option, that can be enabled by the user, under his own responsibility to allow to open Opera inside a FF tab?

If this is not possible, is there a way to to that, but hacking the IETab code, and use Opera instead IE?

This review is for a previous version of the add-on (0.6.1).
