[ubuntu-ar] Firefox no me instala addons y extensiones

[Juan Matticoli]

Buenas

Uso Firefox 2.0 y la version 3.0a8 ambas en Ubuntu 7.10. el problema es
que no puedo instalar nada, ningun addon ni extensión, ni siquiera un
tema. Yo de esto no entiendo nada, alguna idea??????

Les posteo el error:

" firefox could not install the file at https://..... 
Becouse: Unexpected installation error
Revie the error console log for more details.
-203 "

Posteo parte de la consola de errores, lo que esta en negrita parece que
es lo que falla.

// An item entry is valid only if it is not disabled, not about to 

      // be disabled, and not about to be uninstalled.
      var installLocation = this.getInstallLocation(item.id);
      if (installLocation.name in StartupCache.entries &&
          item.id in StartupCache.entries[installLocation.name] &&
          StartupCache.entries[installLocation.name][item.id]) {
        var op = StartupCache.entries[installLocation.name][item.id].op;
        if (op == OP_NEEDS_INSTALL || op == OP_NEEDS_UPGRADE || 
            op == OP_NEEDS_UNINSTALL || op == OP_NEEDS_DISABLE)
          continue;
      }
      // Suppress items that have been disabled by the user or the app.
      if (ds.getItemProperty(item.id, "isDisabled") != "true")
        activeItems.push({ id: item.id, location: installLocation });
    }
