It really bugs me that browsers allow popups to decide whether the top bars get shown. In firefox you can work around this: set `browser.link.open_newwindow.restriction = 0` and force everything to open in tabs. https://kb.mozillazine.org/Browser.link.open_newwindow.restr...

It bugs me further that browsers don't let me decide whether the top bars get shown. Sometimes it'd be really nice to toggle off all the browser chrome and just have a true full-window view of a page (Full-window, not full-screen: in particular if I'm opening multiple pages and tiling them vertically, all that browser chrome starts taking up a lot of space really quickly).

Dear browsers: this is hopelessly backwards! Websites should never be allowed control my browserchrome. I should always be in control my browserchrome. Given that this is already configurable per-window, put that switch solidly in my hands!
