The attack works on both Windows and Mac versions of the open source browser.
The only way to close the window is to force-close the entire browser using either the Windows task manager

Hmm, normally pressing the Esc key rapid fire will cancel the reload-authenticate cycle so you can use Ctrl+W/Command+W to close the bad tab. But few people are versed in the magic of the Esc key.

i am pretty sure mozilla resolved this issue with a htaccess mask month ago - just close the tab.

No, the bug is still live.
If this is the correct bug, Bug 1571003 Basic auth confirmation prompt spam / DOS, then it is to be fixed in FF 72 (or perhaps some dot release, if it comes about).

I posted a live link in this thread, if you're inclined to test, safely, https://www.dslreports.com/forum/r32565 ... ding-users.

This looks to be "fixed" in FF 72.

(The page still shows up, still goes through all its machinations, still uses CPU, but at least with a couple ESC ESC, you can close the page...)

Fix might end up in 70, if there is another dot release.

with firefox 70 +ublock i can close the mask, but then the tab freezes, firefox tell me a page is slowing it down. in firefox 72 closing the tab lakes firefox crash, in firefox 70 i opened another empty tab - still very slow - and close the bad tab. after a small period firefox gets back to normale usage without using cpu. a second test in v72 did same. firefox parent process is spiking, delegating the action to a child process and terminates this one when ready, all fine.

ok - another test with firefox 70 and a brand new profile, ofc sandboxed. nothing changed - i can close the mask with [x] or "Cancel", the page is spiking and thus firefox, but i can close the tab and after some period firefox behave normal as written above. thats what i know that mozilla has set its options for such "uncloseable" pages with a htaccess mask.
