Hello,
it’s me again, this time with a very specific formbuilder problem.
I don’t know if you feel responsible to take care of internet explorer specific aspects 
, but maybe there is a simple solution to this problem, who knows. If so, of course I am happy!
The form works pretty well in all browsers so far. In Firefox it sometimes reports “No valid CSRF token…”, but this can at least be solved by refreshing the page. In Internet Explorer however it reports the following:
“Do you want to open or save “formhandlercdbff83b.json” from “URL XYZ”?”
Can anyone help me?
PS. I will post the issue here as well: https://gitlab.com/kirbyzone/formbuilder/-/issues/
