We have an application running on Firefox and noticed that with new Firefox ESR, Ajax call (XMLHttpRequest ) from js script running on Firefox browser on thin clients seems to be blocked frequently (same call succeed most of the time, but blocked from time to time). Issue was raised starting with Firefox 128.2.0esr), but in general persist with newer Firefox ESR. We tried replacing XMLHttpRequest with fetch which seems making no much difference so far.

Can you look in the inspector at the network request to see why it is blocked?

There should be nothing in the ESR specifically that's different with respect to this.
