firefox portable + plugin "header modify"

[rcmolero]

Buenos días, necesitaría localizar un firefox portable con el plugin "header modify", lo intento hacer pero cuando termino el fichero o cuando entro en complementos me indica que header modify no es compatible o directamente no aparece, cuando lo instalo antes de hacer el proceso de portable me funciona correctamente. ¿Donde prodría localizar una solucion?. Gracias.

# Themes and Extensions - Most themes and extensions should now work with Firefox Portable -- including those that make use of the component registry. A handful will still fail, though. A few things to keep in mind:

* Some XPIs must be downloaded to your PC before installing and then opened using FILE and then OPEN (this is a limitation of Firefox, see Bug 262854). If you can't easily download the XPI locally (like with the Google Toolbar), simply enable your cache temporarily (Tools - Options - Privacy - Cache - enter 1000 and click OK) and then install the extension. Don't forget to disable the cache again after installing. Oddly, addons.mozilla.org doesn't seem affected by this.
