When I tried to reproduce this in opera (which is based on chromium) I wasn't able to do so. But it's only happening with chrome as mentioned by you. The thing here is that the website looks exactly same on both the browsers.
We'll have to look into this deeply.
@QuincyLarson Thoughts?

[DusanSacha]

Could you post the exact link where did you reproduce the error?
I have the same configuration as mentioned in the first post, I don't see any console errors though. (Temporary problem possibly?)

[zuzana-kunckova]

I see the same issue on every beta page. This, for example, is from this link.

This looks like an issue with the Content Security Policy. CC @BerkeleyTrue

[BerkeleyTrue]

I'm not aware of any fonts that we use that are sourced as data blobs. Our fonts are set up as .tiff files.

These are the totality of all our fonts.

I suspect some errant third party extension

[zuzana-kunckova]

Just to update you all, I still get the errors, in FCC, in Beta and while running FCC locally as well. It produces 33 errors every time.

[QuincyLarson]

@zk433 are you getting the same errors reported by @seifsg? Can you look in the staging branch and see whether any of these fonts are referred to anywhere in there? If not, it may be a dependency that's trying to load them.

[zuzana-kunckova]

@QuincyLarson Yes, it's exactly the same issue every single time. And always repeats 33 times.

I looked through the codebase and I couldn't find anything there. But based on some googling, it seems to be related to the Content Security Policy set up: 'font-src': "data:" should be added to it to allow for fonts to be loaded from data: URIs. I did find the content-security-policy-builder dependency, but that's as far as I got since I have no idea what it is that I'm looking for - this is way over my head, sorry!

[QuincyLarson]

@zk433 Thanks for doing this research.

@BerkeleyTrue would using font-src': "data:" like @zk433 proposed open us up to any additional threats that you can think of? If so, it sounds like this might solve this minor issue that several campers have independently reported.

[BerkeleyTrue]

Yes, it is possible that using font-src data would open us up to some vulnerabilities.

Just to reiterate, we don't use any fonts in the form of data blobs. Neither should the page linked above require any fonts other than what we already link to. This is most likely a third part extension issue.

@BerkeleyTrue OK - thanks for the clarification.

@zk433 Can you try to open this in incognito tab with all of your Chrome extensions turned off and see whether you're still able to reproduce this issue?

@BerkeleyTrue , @QuincyLarson , yes 👍 ! There were no errors when using the incognito tab so I went through all my extensions and found that it was the Grammarly Chrome extension that was causing the errors! As soon as I disabled it, errors went away.

Well, that turned out to be a much simpler solution than I thought it would be :). But I learned a lot about the Content Security Policy so time well spent :)

@zk433 I'm glad that worked out.

Happy Coding
