When a link is opened in a new tab, that tab should keep the history of the tab it was opened from.
There used to be a Firefox extension for that, but that now doesn't work anymore because of changes in Firefox. Chrome closed a feature request for that with WONTFIX (https://code.google.com/p/chromium/issues/detail?id=1639).
EDIT: Oh, and also a simple user-friendly way to block autoplay of all audio and video elements. Maybe a "quiet mode" switch or something like that.
