One of the unique features of Opera that other browsers should add is ability whitelist/blacklist most annoyances and vulnerability points for a website. I usually default to everything off and whitelist as I go. - Kill 3rd party cookies + remove all cookies on browser close - No plugins enabled (and permanently disable all unneeded ones like Java). Plugins can be reenabled per site. - kill javascript on really bad sites that abuse it and work without it - Use private tabs and windows for shady sites - kill animated gifs and html5 video autoplay on sites that abuse them Since Opera has a built in way to whitelist sites for each of the above items (or blacklist depending on how you do it), I add trusted sites back with plugins on demand and save cookies for a few sites where not having them will be annoying (banks, etc).
