@rory-aurous Fixed- I had Settings> Privacy and Security> Cookies and other site data> Clear Cookies and site data When you quit Opera ON so I turned it OFF. One of the extensions fault. also deleted that extension.
@sgunhouse Yes thank you, I checked the cookie settings and for some reason throw away option was on. I'm assuming it's some ad-blocker extension's fault. all good now!
@filipgfx Now, if you are referring to a passphrase, you can't recover it. You will need to reset it so that you can set up a new one, but it will erase your synced data from the servers.
In right-side pane, scroll down a little and you'll see “User Interface” section. 4. To disable Tab Islands feature, set the toggle button given next to “Automatically create tab islands” option to OFF.
@kaixchile That's the normal and expected behavior. Opera doesn't have a way to set a home page, you can only set a page or some pages to open automatically when Opera starts and this is what happens.
