[DownloadWith] Error installing in MozillaFirefox

[romildo at uber.com.br]

Hello.

I want to install DownloadWith in MozillaFirefox
running in my Gentoo Linux box. But I am getting
the following response when installing:

  Failed to create downloadwith.jar
  You probably don't have appropriate permissions
  (write access to your profile or chrome directory).
  -------------------------------------
  Error code: 202

I do not know why that is happening, as there
is not any problem with the permissions of
the referred directories:

$ ls -alF ~ | grep -i phoe

Any clues?
