Q:

Can I run two versions of Opera with independent cookies? 

I'd like to have multiple Opera windows open, each using a separate cookie jar.   This is primarily so I can be connected to both my personal google email and my work google docs account at the same time.   Is this possible? 

A:

You don't need to run two instances of Opera for that.  Just open a private tab (right click on the tabs bar and select the "new private tab" option) and load your personal email there, then right click on it and "pin tab".
