it might be more safe, since your data is wrapped in 2 layers of encryption. but if you are this conserned about safety, consider tor maybe?

try the beta/developer version.
http://opera.com/beta

is there a way to disable the mailto fowarding afterwards? because, this is annoying.

After setting gmail.com, or inbox.com to accept all maito: links, opera opens the settings window on startup every single time. this is very annoying, and it happens on all my computers

I'm using opera beta, and the copy function seems to work intermittently. sometimes, i will be able to copy something, but other times, it won't copy even after try 6 or 7 seven times. i have used the black box that pops up when you select something, I've used the right click menu, I've used ctrl+c but none of these work reliably. does anyone else have this issue? I've also seen this issue on opera developer, so they haven't fixed it yet.
