Minor Web Browser (FireFox) Problem

My browser no longer opens some documents/files within the browser like it used to (e.g. opening Word documents directly in the browser, accessing Winamp Playlist (*.pls) audio streams from the internet no longer opens Winamp automatically.) Just happened one day. I now have to save the file to the hard disk in order to open it. Any ideas why opening from Firefox no longer works?

Thats a good question. Now my question is why has mine never done that? Lol. Anybody have any ideas?

you can set firefox to ask you on each file if you want to open it or save it to disk.

But when I click the link, NOTHING happens. Momentary hourglass, then nothing. Already been in those FireFox settings anyway, didn't help.

I was replying to eleanorstang. you probably need to uninstall and reinstall.
