Literally use any window.location.href with an application URI and it no longer works as it used to, instead it gives this error,

First of all, I have no way to provide details. My ex-wife, who is definitely not good on a computer, orders groceries online from Harris Teeter regularly. Today she was having trouble entering an order and called Harris Teeter support. They told her that their web site is now having problems with Firefox and talked her through switching to Chrome. I got the impression the problem had something to do with seeing images of the food items. Wish I could provide more info than that.

Firefox needs to revert this update.

Still no fix?

Links with the format magnet://url need to be changed to magnet:url without the two forward slashes ("//") and Chrome will soon be the same (Bug 1876729).

You can revert by changing network.url.useDefaultURI to false in about:config then restart the browser.

Why don't they have it false by default?
