I have never been able to completely save and restore settings with Opera.
I have never been able to completely transfer my settings to another computer.
Recently I had to transfer settings and passwords to my wife's computer.
She uses Firefox. It was simple and easy.
I used to use Firefox, but honestly I prefer Opera.
It is no longer an issue. I am tired of putting up with Opera's issues with back up and restore.
I am moving back to Firefox.
I also do not appreciate the need to agree to receive emails, just to log into this forum.
I will be immediately blocking all Opera emails and will shortly delete this account if possible.
I am not alone with this issue, but Opera seems to not care.
Too bad for you. Goodbye and good riddance!
