Thanks for the report Benjamin. This sounds similar to https://bugzilla.mozilla.org/show_bug.cgi?id=1719968. Could you test on the affected machine with an upstream build (as downloaded from https://www.mozilla.org/en/firefox/download/thanks/), and let us know whether you're observing the same problem? If so, can you comment on that upstream bug?
Also, is the XPS 13 also running Ubuntu 20.04, or a more recent release?
