Warn me when websites try to redirect is redirecting prematurely
After the latest update (46.0.1), having the "Warn me when websites try to redirect or reload the page" enabled is causing a message pop up when a refresh header is being sent, even if the timeout is something like 20 minutes. We're using the refresh header in the admin area for the browser to redirect the user to the login after 20 minutes of inactivity, but with this option enabled it's giving the message that it prevented a redirect. Clicking "Allow" causes the redirect to happen immediately instead of waiting the 20 minutes for the automatic redirect.
This function works correctly if this option is disabled.
