Firefox version

   128.2.0esr (64-bit)

Operating system

   Windows 10/Windows11 23H2 Septembre patch

Hello everyone,


maybe you can tell me/explain what the problem could be.

In our company we had Firefox version 115.14.0esr (64-bit) and then we updated to 128.2.0esr (64-bit).

Since version 128.2 ESR we have experienced problems in Firefox when trying to access DNN+ pages (with login). https://www.dnn.de/sport/regional/dresdner-sc-denkt-ueber-uebernahme-der-margon-arena-nach-C3IC74MZ6FE43AKGCZJSKUXA3I.html

In Firefox the content is cut off, in Edge it is displayed normally.

With Edge and Firefox 115.14.0esr the page is displayed normally. No AdBlock installed.

In developer mode I see the errors in the versions, so it shouldn't be that.

Cross-source (cross-origin) request blocked: The same-source rule prohibits reading the external resource on https://gum.criteo.com/sid/json?origi...AAAAAAAA&gdpr=1. (Reason: CORS request failed). Status code: (null).

Cross-source (cross-origin) request blocked: The same-source rule prohibits reading the external resource on https://id5-sync.com/api/config/prebid. (Reason: CORS request failed). Status code: (null).

Any ideas? Thank you very much! :)

It was due to the Improved Activity Tracking Protection in Firefox for Desktop. -> In FF was selected by default and also in MSFT Edge. I noticed that Firefox blocks much more than MSFT Edge. So I added an exception for the page and that's it.

Thanks for the support!
