firefox, mozplugger or evince: what messes up pdf's in firefox?

[sean darcy]

On an F10 box updated often, for the past week, if I open a pdf url in 
firefox, evince opens in sort of a separate window which is Always On 
Top (for instance, any Print dialogs can't be seen since they're 
"behind" the window). No window manager stuff ( minimize , close ). Only 
way to close is from the File menu.

I'd file a bug, especially this close to a release, but whose bug is it?
