Hi,

When switching from FF 128esr to 140esr our customers noticed a massive impact in performance for certain webapplications. All Applications effected heavily use pdf-files, users are working mostly exclusive in firefox. Performance is ok when the day starts but gets bad fast. Sooner or later working is no longer possible and firefox needs to be restarted.

The users work on Citrix Desktops, but difference in performance is also seen in Firefox localy (not as bad but its there). Cross-tests with another browser are not possible, because the application works only in FF.

We tried removing almost all policies effective to rule out a specific hardening setting We tried every setting we could find linked to cache (as it seemed related to that) but without success. We collected logs with the Firefox-internal Tools but could not identify a specific Problem.

Any Help is apreciated, thx in advance
