Not sure whether I should bother though: I'd expect something along the lines of "why can't you just use [popular browser names here]".

How to reproduce

1. https://stepstone.de
2. Enter anything in "Jobtitel", press "Jobs finden".

Reproduced, e.g. here: https://www.stepstone.de/stellenangebote--Praktikum-als-Python-Entwickler-fuer-Digitale-Schiene-Deutschland-Berlin-Deutsche-Bahn-AG--7576726-inline.html

Seems to work on first sight with KDE Falkon. No idea why.

[MorpheusMXML]

Just a little Update on this.

Seems like something changed and now no matter what part of the Stepstone website you want to visit i get a ACCESS DENIED.

Access Denied
You don't have permission to access "http://www.stepstone.de/jobs/jobs.html" on this server.
Reference #18.1c501302.1685174545.18215e80

Probably not super helpful but i just now wanted to do some jobsearch and was heartbrokent that my favorite browser isnt working :(

@MorpheusMXML Seems to work fine with Qt 6: #7202 - looks like they simply do something weird server-side which breaks things on purpose (most probably some over-eager WAF).
