In 2003020208 it was spotty.. most of the time it worked, after a while of surfing, it failed. Now in 2003020608, it doesn't work at all. Links clicked externally to Mozilla (urls in Outlook, Outlook Express, etc.) all reuse current browser windows instead of opening brand new windows as they should. Reproducible: Always Steps to Reproduce: 1. 2. 3.

this isn't file handling, but it's law'sh

that was greek to me. law'sh?

Is this going to be looked at?

Reporter, does it make any difference if you turn on supportDDEExec, start and close Mozilla and turn it off again? If it doesn't work, could you export HKEY_CLASSES_ROOT\http key and its subkeys using regedit and attach the file to this bug? I think we need a better pref to turn off reusing of windows anyway..

Apparently someone else also reported this behavior. http://bugzilla.mozilla.org/show_bug.cgi?id=193189

I can confirm this bug, using 1.4 final on Windows XP. The trick worked, iirc, in some of the 1.3 versions, and has been broken in the 1.4rc and 1.4 final versions I've used. As a workaround, deleting the HKCR\HTTP\shell\open\ddeexec key forced it not to use dde for me and gave the desired behavior of external links opening in new windows. Some kind of pref setting to say how dde opened windows are handled would be convenient (reuse, new-window, new-tab), though the prefs window is jammed full enough as it is.

I also have the same problem in Phoeni..er, Firebird 20030714. Tried all manner of reset, restart, etc. I also have TBE installed, if that makes any difference.

Using Windows XP this is also the case.

this bug is also hurting Miranda, which reused the same window and not a new one when clicking on URLs. see: http://forums.miranda-im.org/viewtopic.php?p=71256#71256

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6a) Gecko/20030924 Firebird/0.7+ If I have "user_pref("advanced.system.supportDDEExec", false);" in my user.js, I always get new windows. If I have the default of "user_pref("advanced.system.supportDDEExec", true);" in my user.js, it reuses the last window. Every nightly build of Firebird in recent memory does this.

bill: this is a mozilla bug, not a firebird bug.

I've found this problem in two different installs of 1.5 under Windows XP Professional. It's rather annoying and often leads to data loss. I can't even understand why there ever was a reuse window feature in the first place. I've attached the regfile suggested by Ere Maijala in case it helps.

I see this has been discovered again. see bug# 121969 as it is in many ways related Hey guys? Can we look into this at all? It's been on the table for going on 3 years now... 121969 isn't the first bug about this -- just the oldest not marked Resolved Redundant. I have tried all of the workarounds suggested -- to no avail. This is irritating enough to me that I have been forced to use IE as my default browser. I'm tired of losing the page I was on to get the new URL i typed in the explorer address box. And I'm tired of webpages opening in itty bitty windows that were popups before...

I've been playing around with Windows XP registry. This is the value created by Mozilla when you make it the default browser: [HKEY_CLASSES_ROOT\http\shell\open\command] @="C:\\ARCHIV~1\\MOZILLA.ORG\\MOZILLA\\MOZILLA.EXE -url \"%1\"" I've erased the "-url" part: [HKEY_CLASSES_ROOT\http\shell\open\command] @="C:\\ARCHIV~1\\MOZILLA.ORG\\MOZILLA\\MOZILLA.EXE \"%1\"" I'm not 100% sure whether it's solved the problem but I'd say that it has reduced it quite a lot.

Comment 8 has been working for me for a while now, since my 7/16 comment at least.

I have tested Comment #8 with Mozilla 1.6 (Win XP Pro). It doesn't solve the problem itself. I've also needed to apply Comment #17.

It is same for me (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a2) Gecko/20040616 Firefox/0.8) It is different with FireFox 0.9, always get new windows... this no good for my :-( I hope not to be off topic. (I speak french only). Electron.

confirming this still exists in 0.9 for me. intstalling TBE, renaming/deleting DDEExec key, restores functionality.

Comment 20 & comment 21, as previously stated, this is a Mozilla bug, not a Firefox bug.

>Comment 20 I apologize for inconvenient. I found the good thread. I go to bug# 245747 :-)

This appears fixed in SeaMonkey 1.0 through 1.0.2 with the new "Link open behavior" and "Links from other applications" preferences under Tabbed Browsing. I have the former set to "A new tab in the current window" and the latter set to "A new window". These settings consistently work correctly. I heard it was also fixed in some recent version of Firefox.
