Summary: firefox 3 can't handle local paths in location window
                    [dogfood]
           Product: Wine
           Version: CVS/GIT
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: download, Installer
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Today I tried to install Acrobat Reader,
and for some reason it decided to use the
download manager rather than a direct download.
The download was interrupted (that's another story),
and the download manager left a handy link on the
desktop to resume the download.  The launcher contained:

env WINEPREFIX="/home/dank/.wine-firefox" wine "C:\Program Files\Mozilla
Firefox\firefox.exe" C:\windows\temp\nosget_start_manager.html

That's not going to fly for several reasons:
1) the backslashes aren't quoted or escaped (but that's a different bug)
2) Firefox 3 on Wine doesn't seem to recognize
local paths as valid URLs; typing
   c:\foo.txt
into the location window yields errors like
   Firefox can't find the file at /c:/foo.txt.

Firefox 2 doesn't seem to have this trouble.
(I have not verified that Firefox 3 can handle c:\foo.txt
on Windows, but I'll eat a box of doughnuts if it can't.)
