Many sites, I go to make an account, can't see captcha, then things get hung up.

For example: https://www.openmailbox.org/#register "I'm not a robot" box is not visible.

Using 38.0.5 adblock plus, flash, quicktime, java, the standard stuff.

Try disable AdBlock and NoScript if you have installed too, some time they can block captcha.

Note that you always need to remember that if you use extensions that can block content that you need to check if such an extension isn't blocking wanted content if you notice that content is missing and fails to show.
