WARNING LOT'S OF SCRIPTS WON'T WORK USE OTHER ADDON LIKE TAMPERMONKEY OR VIOLENTMONKEY. Review for version 4.11 now 31 months old. It refuse to install some scripts and that will get worse because firefox evolves. On top of that I wrote a local script. Grease monkey validates the name but use it own name. ( unnamed script 123455 ) and that can't be changed. When I made a seccond script I couldn't be saved beccause "unnamed script name space is in use. This addon should be removed because script writers are dependent on it and this one has become a disgrace.
