1648322 - Firefox 77.0.1 blocking pop-ups when pop-up blocker disabled

Status: RESOLVED DUPLICATE of bug 1176510

(Core :: DOM: Events, defect)

Description

[Duncan Bayne]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:77.0) Gecko/20100101 Firefox/77.0

Steps to reproduce:

1. Disable pop-up blocking.
2. Navigate to a site containing many URLs that I want to open in new tabs.
3. Execute the following code in the console:

$('a').map(function(ix, el) { if (el.href.startsWith("http://example.com/url/")) { window.open(el.href, "_blank"); }});

Actual results:

Many new tabs open, but eventually, Firefox displays the message "Firefox prevented this site from opening more than 100 pop-up windows."

Expected results:

Firefox should have honoured my configuration change, and opened as many pop-up windows as I requested.

(This may be a regression; a similar bug was fixed some years ago: https://bugzilla.mozilla.org/show_bug.cgi?id=260264).
