Thanks you!

Which plugins folder?

My USB installation of Firefox Portable seems to have two separate folders for plugins:


Both include the text file instructing users to place plugins there. I'm guessing maybe the implementation changed at some point, one of them is left over from a previous version? Anyway, are both of these necessary, and if not, which is the correct one to keep/use?

See what is being used

Go into about:config and set plugin.expose_full_path to "true"

Then go into about:plugins

You'll be able to figure out the location that loads (probably both places, giving dupe listings) and you can proceed from there. Also probably see some listings from the host computer, too.

use the Data one. DefaultData is exactly that - default data, used when you need to reset your settings for any reason, etc. Yes, both are necessary, but the correct one to use is Data\plugins.
