Firefox extensions removal

Had trouble today installing a fresh « Firefox 0.9 » version.
My last problem was triying to remove « pnh toolbar »:, wich did not show in the extension.
« Piro »:http://white.sakura.ne.jp/~piro/entrance/_profile.html (the creator of TabBrowser Extensions, a.k.a. « TBE »:http://white.sakura.ne.jp/~piro/xul/_tabextensions.html.en#download) has a very good « Mozilla extensions uninstall help page »:http://white.sakura.ne.jp/~piro/xul/doc/installation.html.en#uninstall (written forTBE, but works for all extensions), wich shows what I found myself, and more… Check also his « TBE FAQ »:http://white.sakura.ne.jp/~piro/xul/_FAQ.html.en#tabextensions & « forum »:http://white.sakura.ne.jp/~piro/xul/forum/forum.cgi.
