Hello, So I've been trying to activate local links which would open a local directory in file explorer. I'm trying to do this on a wiki based on MediaWiki running on a local Nginx sever(laragon). The links work as intended on IE, i.e, I click on the link and it opens a file explorer window with the linked directory. However nothing happens when I click on the link using Firefox. Instead I get this error message : 

   Security Error: Content at http://url.com may not load or link to file://///.../directory.

I have tried adding these lines to prefs.js but it didn't have any effect : user_pref("capability.policy.policynames", "localfilelinks"); user_pref("capability.policy.localfilelinks.sites","http://localhost"); user_pref("capability.policy.localfilelinks.checkloaduri.enabled", "allAccess");

Is there any possible workaround to activate local links without using an extension?
