I'm using Firefox 63.0.3 and was trying to follow unhosted.org
When shift-clicking on the "data url" link, I am redirected to a new firefox window with "about:url" on the address bar.
In this page right clicking shows nothing and there is no shield showing up by default on the browser.
When I go to settings and click the shield entry ( Content Blocking), i have no idea what I should do.
If I just click on the link I stay on the same page.
To access the editor, I add to right click the link copy the link and past it in a new address bar.
Anywhere where I can edit this page so other users may spare some time with this ?
Cheers and Thank you for your work,
