How can I change my user agent?

For some reason I keep getting blocked in many websites (cloudfare hosted sites) because of my browser signature.
I'm using Opera 25 Developer and I've tried following this tutorial and to no effect: http://www.technipages.com/google-chrome-change-user-agent-string

Thanks.

I can enable this mode normally here by clicking the "smartphone" icon that appears in the Emulation tab.
