For those who didn't want to get involved with my rant here is a firefox secret that is worth knowing.
Or ~/.mozilla/plugins or /usr/lib/mozilla/plugins or ....? As someone just starting with Fedora Core 6, I had a difficult time getting the plugins installed and working, and then two time later updates messed me up, and the last time I am not sure what messed it up. But because I am using my old 466Mhz Celeron with 256Mb of memory I don't want to waste developers time with a bugzilla against this old, slow, memory constrained system (even though it is more powerful that the CRAY that was used in the 60's.)

Now I will tell you a secret. If you go into about:config you will see that the configuration: browser.download.hide_plugins_without_extensions is set as true by default. Only when it is set to false can you see what you want to see in the: Edit->Preferences->downloads->view & Edit Actions. With this set as true you are flying blind with plugins. Why does fedora not distribute this with the configuration set properly. How would you know about this?
