This extension does not work with tumblr at all. At first it just denied me the ability to see the post screen when I went to make a post. Then it began to do the same thing to reblogs. At this point, it actively goes to a black screen after approximately 1-2 seconds of seeing any page. I turn this single extension off, presto, everything works again. Turn it back on, boom, all black screens again. Since I use tumblr all the time, this means I cannot use this extension (that I dearly want to use!). Please please fix it so I can use tumblr again. Thanks!
