While trying to figure out why RefinedGithub was causing me some issues on a non-GitHub website (gcc.gnu.org to be specific), I noticed that RefinedGithub has "Access your data for all websites" under "Optional permissions for added functionality" enabled on my browser. I may very well have enabled that permission myself at some point, but if so, I forget why. If there was some sort of prompt or dialog that showed up explaining why the extension wanted the permission, then I've forgotten what it might have said. If documentation for why the extension might want this browser permission is already available, it should be made more prominent, and linked to from (more of) the places in which a user might look for documentation.
