GNOME Yelp input field also same behavior of Firefox.
So, I think this is by design.

Yes, I noticed that, for example Quick Search in Debian's Synaptic Package Manager also behaves same way. But on the other hand, Opera web browser does not, renaming files in Gnome File Manager does not and many other examples.
Would be great if it could be a configurable, because currently it's quite inconvenient (at least for me)

gedit’s file open dialog and Xfce’s run dialog on Debian testing behave the same way.

Advice: use WebM or Ogg/Theora for screencasts.  Those are free formats, and can be played with Firefox.
