Submitting POST forms on certain websites returns a blank page
Some websites with POST forms return a blank page when I submit the form. The data apparently gets submitted, so depending on the website I can refresh the page and it works fine. But some websites, this completely breaks the functionality.
Most recently this happened to me clicking the "Ship to this address" button on Etsy (which is a site-breaking situation and refreshing took me back to the same page). Then I came here to register an account and, well, funny story, it actually happened when I clicked the Register button after filling out a username, password, and email address (but refreshing worked).
Possibly related: around the same time this started happening, I noticed that 307 redirects would give me a blank page saying "Document has moved [link]here/link," and I'd have to click "here" to move on, as opposed to the redirect automatically happening.
I've tried disabling add-ons and it hasn't helped.

Usually a 307 redirect has a special warning, as discussed in this thread: very frequent popup: This web page is being redirected to a new location. Would you like to resend the form data you have typed to the new location?
Is it possible that Ghostery's redirect feature is affecting these posts? It's a common design pattern to redirect after post to better manage the user experience.

Clicking the Post Question button just now also sent me to a blank page, and refreshing just took me back to the Post Question form. Fortunately by confirming my account through my email, my question got posted. Otherwise I would have had to post on this forum in Chrome. The horror.
(EDIT: But the Post Reply button worked perfectly) (EDIT 2: Update Answer did not)

I...um...I disabled Ghostery, then re-enabled it, and the problem isn't happening anymore.
Well then.
Sometimes there's no good explanation. (When restarting an acquaintance's phone by removing the battery and putting it back in again, I always make a show of blowing the stray electrons off the connector.)
Oh, well, that's just because phones are powered by Nintendo cartridges. Everyone knows that.
