How are you installing?  tarball, sea, rpm?

Reporter, If i'm not mistaken i think your issue is this: 
The Linux installer tells you it has found a folder with existing Mozilla
installation and asks you if it's ok to delete this folder. This means that if
this folder contains your plugins they will also be lost. 

Before you install a new Mozilla build, copy the plugin folder from your current
build to /home/YOURUSERNAME/.mozilla/plugins 

Mozilla will also look for plugins in this folder so you wouldn't have to
reinstall each time.

(i think there's a dupe on this somewhere as well)

Reporter: are you deleting directories or something before you perform the new
install? Or are you installing in a separate location each time? Or are you
overwriting existing installs?

The installer doesn't touch the home directory, but the old default plugin dir
was  under the install dir, so some still install plugins there. To avoid
deletion use the ~/.mozilla/plugins dir of course.
