I use the firefox-mac-pdf plugin to view pdf files in Firefox. However, this only works some of the time. Other times, when I click on the link, I just get the blank screen. I'm sure it loaded, since Safari (with Adobe Reader) loads the same file in under 30sec while I left FF didn't load it in the 10min that I left it running. There doesn't seem to be a particular pattern as to which files I loads. I tried reinstalling both FF and the firefox-mac-pdf plugin to no effect. Any ideas? Thanks!
