Description James Socol [:jsocol, :james] 2012-01-26 08:58:55 PST
Dragging and dropping a URL into blank space in about:newtab doesn't load the URL. Dropping it on the location bar or tab does.

1) Open about:newtab
2) Drag a URL from another application
3) Drop it in empty space (i.e. don't add it to the list of sites)

URL loads in tab

Nothing happens

Using the latest Nightly builds on Windows 7 (checked both the 32- and 64-bit builds).

Similarly, there's no effect when you drag-and-drop an HTML file or an XPI file onto about:newtab.  (the latter is mentioned in bug 722672)

Note that this works in both about:blank and at "real" web pages (e.g. at ).
(that is to say, the dropped file gets loaded)
Comment 2 Daniel Holbert [:dholbert] 2012-02-03 15:50:06 PST
Setting OS --> All, as I'm encountering this on Linux as well
Mozilla/5.0 (X11; Linux x86_64; rv:13.0a1) Gecko/20120203 Firefox/13.0a1

Also: this seems to work correctly in at least one instance -- drag-and-drop of a highlighted text selection. If I have a URL in thunderbird or gedit, I can highlight the text of the URL and drag-and-drop that *selection* into about:newtab, and the URL will be loaded.  (It doesn't work if I drag an *un-highlighted* linkified URL from thunderbird, though, as noted in comment 0.)

patch v1

When dragging new tab sites we need a Mac specific workaround to prevent a 500ms delay before the tab gets dropped. There are two changes:

1) This workaround is now really Mac specific (#ifdef).
2) We only need this when dragging a 'site', not for external drops.
Comment 4 Tim Taubert [:ttaubert] 2012-02-04 07:08:58 PST
Forgot to mention that (2) is the actual culprit because why we currently don't accept drops properly.

I think this could just be document.addEventListener instead of doc.addEventListener

Verified with steps from comment 0 on Firefox 13, today's Nightly. URLs are now loaded when dragged into about:newtab.
