I am not sure, either. I no longer use Chrome, Chromium or Vivaldi due to the strange bugs. I ditched Firefox a few times; but it is what I use now simply because it generally Just Works.
You might check on the Chrome or Chromium support boards where there are folks much more experienced in the ins and outs of the Browser. That Firefox does work properly shows that this is not Zorin OS side.
This is not a "not our problem" response as much as it is an "I am utterly unqualified to try to help" problem.
It may be that other users here are better qualified, but I would check the Chrome forums anyway just for a faster chance at a solution or suggestion.
