I’ve been getting a lot of support emails about this, so I will address it here also.
If your queue isn’t posting on time (or at all), this is not a Missing e problem.
Missing e cannot interfere with queue posting. Once a post is in your queue, it is up to the Tumblr servers to post them on time. It is not possiblefor a browser extension to interfere with something already there.
Instead, you can wait for Tumblr to fix the problem or you can try your luck contacting Tumblr support: firstname.lastname@example.org
