I have just (10 minutes ago) allowed updates to Firefox, Thunderbird and Opera.
The first two are fine, but Opera (12.15) is like a brand new installation.
This is my main browser and email client, so I have just lost all my contacts, saved settings, passwords, history and Speed Dial.
Is there any way to roll back to previous version or to recover my settings?
I wanted to post a warning to prevent anyone else experiencing this.
