So is this just asking for the additional "block all popups" option? We have that in the core, with pretty fine-grained control over when popups are allowed, exactly. See the dom.popup_allowed_events preference. This bug sounds like it's just asking for UI for that, which would very much not be a core DOM issue. I should note that chances are this option would also break things like the search result links on Yahoo search, since they open the page in a separate window from the search results.

I interpreted this report as Internet Explorer being more efficient at blocking pop-ups, right out of the box. I missed the “option of ‘block all popups’” buried in the Actual Results where it doesn't belong. > I should note that chances are this option would also break things like the > search result links on Yahoo search, since they open the page in a separate > window from the search results. user_pref("dom.popup_allowed_events", ""); user_pref("browser.link.open_newwindow", 1); user_pref("browser.link.open_newwindow.restriction", 0); That still leaves the following, which can be worked around by adding the site to the pop-up blocker exceptions. Bug 918780 — it also blocks the file picker for uploads, with no way to open it. Alternatively, the requested feature is provided by add-ons like the following: https://addons.mozilla.org/firefox/addon/strict-pop-up-blocker/

Yeah, that's a problem. Hard to have it both ways, because sites can abuse the filepicker popup just like they can window popups.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
