When I looks at Edit--Preferences--Downloads, I see a list of plugins that looks like this: PDF PDF File acroread Windows WMV File gmplayer DOC DOC File openoffice.org-1.9 That is what I want, and it reflects what I have set by checking the "always use this from now on" checkbox, when offered the option. But when I click on a link for a wmv, firefox offers totem as the default; when I click on a PDF, it offers kpdf as the default; and when I click on a DOC it offers oowriter (v 1.1.3) as the default. I have to go search for the app I really want every time. So it looks like Firefox is writing to one settings file, but reading from another. This is Firefox 1.02, installed and updated regularly via yum. I only noticed the problem pretty recently, maybe in the last month or two. Maybe it's related to a recent firefox update? Any suggestions? I tried grepping through ~/.mozilla/firefox for any files containing "totem," just to see if I could change the list of helper apps manually, but I couldn't find anything that included totem in the first place. Thanks, Matt
