What is Firefox asking you to "allow"?

The Message is:- "Firefox prevented this page from automatically reloading" "Allow"

This has appeared on other sites that I have visited and by clicking 'Allow' I am able to reload but not, apparently, with this one.

Regards

See Advanced panel - Accessibility, browsing, network, updates, and other advanced settings in Firefox

Firefox is asking me to "Allow" the page to open that would allow me to upload a video to Facebook. But no matter how many times I click "Allow" , it WON'T! ... The message just comes back: "Firefox prevented this page from automatically reloading". Why?!

@ Cor-el: Then what?!

Did you check that setting and make sure that there is no check mark?

If the setting is OK and you still have that problem then check the extensions.
