@leocg Sicronization was always enabled, and the folders disappeared when I installed one in the OS. I solved the problem by importing from another computer that was logged into my account. I exported everything and I cared for my current machine.
@leocg Sorry for not replying. For some reason the message landed in Spam (Gmail is starting to get on my nerves). I think you might be right, they are just notifications on the websites themselves. That's highly annoying. I wonder if there's an addon that might disable those.
As far as I'm concerned, the purpose for a VPN is to provide security when you have an insecure connection, and Opera's VPN does that. If you take your laptop to some internet cafe that has open wifi and don't want the guy at the next table snooping on your personal data, it does that. If said open wifi happens to have a filter that won't let you access your game site, it also gets you around the filter. If you're trying to use it to get around country restrictions on streaming video - Opera's VPN may not do that since it doesn't have that many exit nodes. How much do you want for a free service?
