Content-Security-Policy is very nasty one and some wrong move can make your site unusable. Firefox in console shows 2 blocked eval ("script-src") elements. But I do not see what is blocked.

Ok, I've found the reason for the blocked eval's. In my case it is the extension 'Tampermonkey' which causes the logs. Good to know that there are no issues related to the scripts included on my site :)

Yes, I don't know either, but the site seems to work without any issues, so I will keep the strict rules active. I don't use any eval's and I already checked all included libraries. Looks like it's a Firefox bug, all other browsers I tested don't show that log.

Wow! You sure are fast at fixing things!

If you made a better editor than what is on Steemit, there may not be any reason to use steemit at all any more. If Steemworld is an indicator of your abilities, I have no doubt that the editor will be great.
