@blackbird71 Fast forward 3 years and im facing the issue reported by the OP.

Its ridiculous to have such settings as default period.
One thing is to import bookmarks. Other thing is to import my credential in order to give me a chance to easily starting a new session;

Now importing my credentials and creating a session on my behalf just because i installed it sneaky and invasive, and on top of that it decides to manage my sessions across all browsers, i logout from Opera and it also logs me out on chrome, its retarded to say the least.

I used to have high regards for opera but all respect i had is dead now, i cant entertain this crap. Its way too invasive, im ditiching this browser and not looking back.
