This was my reply to someone having outlook login issues after doing a google search for a portion of the injected code appearing in my Userstyle CSS scripts as I installed them:

"This appears to be caused by the firefox addon Refined-Github. Turn off the permission "Access your data for all websites" on the permissions tab and it should fix it. For me it was inserting extra code to userstyle CSS scripts from userstyle.world and some already install userstyles in FireMonkey. I realized looking at you post what the "RGH" CSS handle was for Refined-GitHub."

How to replicate the issue + URL

Enable the "Access your data for all websites" permission.
Install a userscript from userscript.world into FireMonkey or apparently try to log into outlook.com and the follow code appears (note, this has been formatting via prettyprint):
