We suddenly started seeing fingerprinting issue. What could be the reason? Most of our scripts are general JS and CSS scripts. Is there any link where I can check why we are seeing this error for specific URLs?

Unfortunately I can not share screenshot or URLs here.

I don't know what you mean by this:

Do you mean that a script is being blocked as a fingerprinting script? What is the message associated with that (you can anonymize the script address)?

yes the script is being blocked from loading with the error message (Fingerprinting)

You aren't confusing this with Enhanced Tracking Protection ?

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content. You can click shield icon for more detail and possibly disable the protection. You can check the Web Console for messages about blocked content.

we are seeing this as part of Enhanced Tracking Protection enabled in Firefox (which seems to be enabled by default).

It is working fine when we disable it.

As far as I know, Enhanced Tracking Protection lists blocked URLs after confirmation of tracking behavior. Have you tried hosting your script on a different server or under a different name? I can't figure out where the list is or how to search it.

Thanks for the quick response. All other scripts load as expected from other domains. In fact the image files also load fine from these domains.

One other thing to note is while most of our customers reproduce this, some of us were not able to see this error. Reaching out to this community to see if we can get answers to below questions:

1. what is the process to unblock these domains names? 2. Is this being rolled out in phases and only few customers are affected or is it rolled out to everyone on latest FireFox version? 3. Are there any other ways to reach the Firefox team to resolve at the earliest?

See the about:url-classifier page.

This is helpful.

I was able to search for the URL that is being blocked and I see that it is coming from two providers. Interestingly two things happened when we clicked on Trigger Update.

1. For me it started working (not blocking) 2. for some of my colleagues who was not able to reproduce started seeing issues

Is there a way to ask these providers to update the list and exclude the domain in question?

Attached trigger update image.
