Doesn't work for me, sorry to say.

My only complaint about this addon is that it's too legible.

works just as advertised

This extension really slows down Firefox. I had to uninstall it.

I absolutely love that the tweets look like they sound !

Very clever add-on. My only issue is that it's hard to read in Night mode. If there was a way to switch to a higher contrast color in night mode that would be awesome.

Unfortunately while I love the premise of this add-on, I've found it interferes with too many websites in making things just not work. For instance, with this addon enabled, you can't see the buy buttons for You've Got Crabs.
