DHL parcel tracking does not load on Firefox if the user agent is faked as Chrome. Specifically, the JSON data URL https://dhl.de/int-verfolgen/data/search?piececode=UG000000000DE&noRedirect=true&language=de redirects to error https://dhl.de/de/toolbar/errors/fehlermeldung.html if the UA is not as expected. I know I'm not using the system as intended but I don't think relying on UA is good web design. Should I report this to DHL? Also, how does it work on Chrome with the same UA? Does it check if my browser is really Chrome in other ways? (edit: JS+cookie from visiting HTML page first)
