Mozilla versions from 0.8 to 0.9.1 (others not checked) allow user to drag the link and drop it on other apps. In these versions of Mozilla, the list of data formats of this DND operation is the same as list of data formats for plain "select any page fragment then drag and drop it" operation. It would be much more beneficial to add yet another data format in case just the only link is being dragged - to allow drop targets (i.e. other apps) to distinguish just links from fragments of arbitrary html code. In particular, netscape 4.x marked data with _NETSCAPE_URL format in the case of the only link being dragged - and that format is pertty supported by Gnome Midnight Commander (dropping such link to the desktop would create a shortcut, activating which that URL will load) and probably other file managers and programs. I suggest providing data in the following additional formats: _NETSCAPE_URL - just the link target _MOZILLA_LINK - same as currently provided in "text/html" format (the point here is the name of format is different - that allows apps to distinguish fragments of html code from information about the link only. And the data in other formats Mozilla currently provides dropped things.
The general idea of this is covered by Bug 41447 and one of it's duplicates Bug 74869. *** This bug has been marked as a duplicate of 41447 ***
<slapping self>. I meant to mark this as a dupe of Bug 41477 - [RFE] Support drag and drop of arbitrary content, inc. plugins.
Doing it right (hopefully) this time... *** This bug has been marked as a duplicate of 41477 ***
May God have mercy on us all. The 212 bug spam-o-rama is Now!
