Brecht contributed this feature to Tweak New Twitter [1] if you want to turn your timeline off and have to intentionally turn it on again, so you can't casually browse it - it's in the Experiments section at the bottom of the extension's options. (At the time of writing I'm still waiting for addons.mozilla.org to approve a new version which fixes issues caused by a markup change Twitter made yesterday, so in the Firefox version you can't currently see the separate timeline Tweak New Twitter moves Retweets into by default) [1] https://github.com/insin/tweak-new-twitter#tweak-new-twitter https://github.com/insin/tweak-new-twitter#tweak-new-twitter
