Only Browsing Past — twocatsinatrenchcoat

This extension stops Twitter from forcing you to make an account when you're browsing without being logged in.

If you're not a Twitter user and just want to check what your friends have been up to from time to time, you've more than likely noticed the glaring blue banner that immediately pops up at the bottom of the screen, not to mention the pop-up that stops you from scrolling further once you've hit a certain threshold. This extension removes those intrusive elements and lets you continue scrolling.
