Details

I was downloading a large file (1.5GB .mp4 video) on my Windows Nightly, and it made the browser incredibly unresponsive (as in, seconds at a time). I managed to grab a profile of it, see the URL. I was downloading to an SMB network share on my LAN (which is gigabit ethernet).
I'm not sure if this is in the right component or if it ought to be in Networking.
Based on your profile, I think this might be a duplicate of bug 789932, but I'm not sure why nsExternalAppHandler was invoked if you weren't trying to open the file
That sounds right. Gavin mentions in bug 789932 comment 2 that we'd hit this for almost all downloads. IIRC I got the "Open With" dialog for this download but selected "Save".

IIRC I got the "Open With" dialog for this > download but selected "Save". Yeah, any downloads that go through that dialog (whether for opening or for saving) hit that code. The download cases that don't are e.g. "save page as" and "save target as".
