From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.3+) Gecko/20010824 BuildID: 2001082421 Some links are of the form : HREF="mailto:mozi@free.fr" If I click on such a link using the middle button of my mouse, a navigator window appears with the url bar : "mailto:mozi@free.fr", and then, a mail composition window appears. Reproducible: Always Steps to Reproduce: 1.go to a page with a mailto: link 2.click on it with the middle button of the mouse 3. Actual Results: 2 windows appears : a navigator one, and a mail composition one. The navigator one just stays open. Expected Results: Only one window should appear : the mail composition one.

Confirmed. Over "mailto:"s a mouse middle button should be treated like a left button.

could this be related to/dup of either bug 58826 or bug 61163?

This bug could probably be considered either a duplicate of bug #61163 or dependant on it...it's the same problem manifested in a different way.

Bug #58826 also appears to be another manifestation of the same bug.

Even when you click on a href="javascript:command" link with the middle mouse button a new window is created, although the "Open in New Window" command in the popup menu is hidden; execution of the JavaScript command is expected. Is this problem related to this bug or should a new bug record be created?

Update: see bug 70501 for javascript:

this bug is still in the RC2 Mozilla Mozilla 1.0 Release Candidate 2 Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc2) Gecko/20020510

this bug is still in RC3 Mozilla 1.0 Release Candidate 3 Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc3) Gecko/20020523

this bug is still in mozilla 1.1a Mozilla 1.1a Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1a) Gecko/20020610

Verified as of 1.1a. Note that the problem is bigger than just mailto:. Many other links (javascript, target="_blank") open their own windows. Mozilla, I feel, should be smart about this, and do what the user means (one new window), rather than blindly open two.

Bug is GONE ! ( at least on LINUX ) When I click on "mailto:" link ONLY one window appears, the mail composer.. which is the expected behavior!! Thanks mozilla guys and gals !! Mozilla 1.1b Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1b) Gecko/20020825 The owner should CLOSE this bug

OOOOOOOOOOOOOOOOOOOOOOOOPPPPPPPPPPPPPPPPSSSSSSSSSS.... I was wrong... bug is still HERE !!! I did not notice two(2) popup WINDOWS, because I have selected in Preferences - Tabbed Browsing - Middle-click Open tabs instead of windows So, what happened ? I got another tab + email composer when I clicked on "mailto"" link. AGAIN: bug is still here and it is healthy

It is time that I go to bed... It is really very LATE or very EARLY (00:35 AM). I have to correct my self for the second time. BUG is GONE (when the user clicks with LEFT mouse button) ONLY one(1) window pops up.... but when the user clicks with a MIDDLE mouse button two(2) windows pop up. So, this is behavior is acceptable... Yes, it would be nice if the click with MIDDLE mouse button on "mailto:" would NOT bring on the screen two(2) windows.... ooh well.. we can not have everything .. as I said, the current behavior is OK, it is not perfect but it is OK

I noticed someone flagged this "Component: XP Apps" I would just like to say that this MISFEATURE (Since its apparently intentional in the code, its not technically a bug, it works as designed...) applies to all Linux versions that I used myself. I've also seen identical behavior in Windows ME and Windows 98SE. I am "NOT ALLOWED" to change this to "Browser-General", but it should be changed. This is not an XP or even Microsoft-specific problem at all.

Jason: "XP Apps" doesn't mean "Windows XP", but this component covers Mozilla's cross-platform, cross-application application framework.

Also sometimes webmasters put links to pdfs to open a new window, since they are expecting the acrobat plugin to be used to view the pdf inside the browser. Since I have an external view, not the plugin, I get an extra blank window. Should this bug be assigned to someone? It's still NEW

*** Bug 253366 has been marked as a duplicate of this bug. ***

for those usign keyboard opening mailto: links in new tab/window (CTRL/SHIFT) creates a new unespected and empty tab/window. this happens also on other out-of-the-browser protocols.

Oops.

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9pre) Gecko/2008033101 SeaMonkey/2.0a1pre I'm still seeing the behaviour described in comment #0, except I get a new tab with "undefined" in the URL bar, then, in addition, a mail composition window. The difference may be due to the fact that I prefer new pages to open in a new tab rather than a new window whenever possible. Since bug 61163 is supposedly WFM, I suspect this might be a dupe of bug 58826 (both mentioned in comment #2).

Resetting A+QA on long-inactive bug.

This is also reproducible when invoking mail composition from the command line: "seamonkey.exe -compose ..." works as expected, only opening the compose window; "seamonkey.exe mailto:..." opens also a new tab or browser window if "Open links passed from other applications in" is set to "A new tab" or "A new window". Thus, the mailto: link is primarily treated as URL and only then examined more closely if there is actually something to do in that window. The command-line instance could be considered as a separate bug, but given that various middle-click bugs were duped to this one, I'd assume that the root cause of either of those bugs is identical with the command-line manifestation.
