Run Greasemonkey on html files located on the local filesystem?
Since a couple of releases there are two new 'hidden' preferences:
greasemonkey.aboutIsGreaseable
greasemonkey.fileIsGreaseableThe default value is "false". If you want Greasemonkey to run on file:/// urls, you have to set the second one to "true" (in about:config).
Quoted from here:
tampermonkey
If you're here for the same reason I am, which is -> looking for the tampermonkey equivalent, (and you're using Chrome)... go to Chrome Preferences -> Extensions, aka chrome://extensions/, and you'll see Allow access to file URLs
