Hi, I don't know whether this will help, but I am an Opera fan from windows, just learning linux now(MDK9.1).
Do a seperate install, not an upgrade, in windows they run as two seperate programs altogether and are quite happy running simultaneously.. Then you can copy your addresses across, but it is best if you set up preferences seperately.
Like I said, this is for windows, maybe the same for linux.
Cheers
Asif
