I try top open for instance ppt files from a web page. They might open in .txt or .zip of .htm etc. I try to associate the filetype with the right application but can't find the filetype in the dropdown list of "Content Type" under tools - options. The "Content Type" list begins with Adobe Acrobat Document and goes through a list of application/... then shows

audio/x-pn-realaudio-plugin

irc

ircs

mailto

none

Podcast

Shockwave ...

Shockwave ...

Video Podcast

Web Feed

webcal


Tried getting rid of mime and restarting. No good Tried uninstalling and reinstalling Firefox. No good.

Any ideas?

Still investigating this, I found that Powerpoint 2003 was added to the Content Type list (sometime today) but not Powerpoint for pptx files. Then I went through some of the Basic Troubleshooting steps, and, after Reset all user preferences to Firefox defaults, many of Content Types, including Powerpoint have disappeared.
