Looks like I was 4Minutes off x)
Im using Windows 7

Ok, i cant edit my comment but whatever
I just created a new user account with administrator rights, and everything, Chrome or Opera works perfectly fine there... any ideas? (;

I don't have any Data Cleaner, the only thing maybe coming close to this kind is Avira.
Interestingly enough, even on sites without https (Twitch.tv in example) I get logged out.
And also it doesn't save passwords. I click on "Save password" and even if i go into the settings after I saved the Password, it didn't get saved.

Also the reason why I'm not using chrome anymore is exactly this problem, which acts the same in Chrome, but in Firefox everything works perfectly fine... I already asked in Google Forums, no one seems to know there exactly.. And yes, I did a virus scan, nothing detected.

Hello Guys, I recently downloaded Opera, because i had some problems with chrome, but while im enjoying the browser a lot, I face a really annoying thing.
Whenever I close my browser fully it logs me out of everything, which i had ticked "remember me".
Also it deletes all my saved passwords / doesn't save passwords despite me clicking yes to save them..
Any help?

Ty in advance
