So what error detail that is leading to cause this problem your having?

Please reset these prefs via the right-click context menu to the default value. These prefs are there for a reason and you shouldn't be modifying them.

What issue(s) do you have that makes you remove a restriction?

There's no way for extensions to inject content scripts into pages on addons.mozilla.org.

No error comes up. Just that when i use an addon to theme pages (Dark Reader), pages like addons.mozilla.org remain unthemed. I tried this before I had reinstalled ff and it worked. For some reason now it doesnt work which is very strange.

Why should I reset them??

No offense but youre wrong. Before I reinstalled FF I was able to theme addons.mozilla.org with the same version of FF.

I guess I should test for myself before making pronouncements and not rely on other posters...

If I clear the restrictedDomains preference

and create a new boolean preference named

privacy.resistFingerprinting.block_mozAddonManager

and set it to true

and then reload an extension's page bypassing the cache,

the content scripts do get injected as you said in Firefox 63.0.3.

Now... to get back to normal.

By the way, a safer way to dark theme privileged websites is ShadowFox. https://github.com/overdodactyl/ShadowFox

I tried to install this but win defender warned of a possible risk.

And I cant find this addon in the addons.mozilla.org. Why is that do you think?

It doesnt install through ff since its an exe which is strange. Any thoughts?

Is it safe?

ShadowFox installs through the optional userChrome.css and userContent.css files. It is a style rule override, not an extension. Please read through their documentation for more info.
