[Kendoori]

In some cases Zimbra desktop (Ubuntu 9.04) complains upon trying to open attached PDF files. The error message is part of a dialog that says "Download error" in title bar, and the displays

/tmp/name of file.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences.

I just upgraded to FF3.5, which may be the issue. Acrobat files open properly within FF3.5. Acrobat files also open properly from file system.

I have tried changing the settings in Firefox to "always ask" with no effect.

Any suggestions?

I'm not an FF user, but doesn't it have a spot to set helper applications by filetype? You should be able to specify in there that pdf files use a specific application.
