I accidentally pressed "Allow" for a webpage when the popup with "Firefox prevented this page from automatically redirecting to another page" appeared, I would like to undo the "allow" that I did, but can't find out how.

Try this:

Then :

  1. click Firefox button and click Options -> Advanced -> General -> Remove Checkmark from Warn me when websites try to redirect or reload the page
  2. Click OK on Options window -> Restart Firefox

This is not the same problem, unlike him/her I want to keep the popup on this webpage. Just clearing the cookies (not even cache) was enough, problem solved... – Timo Huovinen Jan 5 '12 at 13:28
Glad it helped though. Thanks for the feedback – JMax Jan 5 '12 at 13:31
