un-useable in Linux Rated 1 out of 5 stars

can not see the icon even I added that string pref, I'm in Linux with En Firefox.

For English you need to create the mentioned preference as a "string" pref. Also, the toolbar button is automatically placed on the Add-on Bar (ain't gonna see it if the Add-on Bar is hidden), not placed in the Palette as I would have expected. "About this Add-on" comments on the /en-US/ addons website should be in English.
