pdfjs.enableScripting BOOLEAN True <=== Javascript-inside-a-PDF support
The PDF reader module may itself be written in Javascript, but
there is also interpretation of Javascript within the body
of a PDF file, which is also supported. The name of the code
module is "pdfjs" but in the documents themselves, the
Javascript in there can be supported.
Even if you use "mutool" and decompress a PDF with Javascript inside,
the code is still not recognizable to the eye. Which is an
unfortunate design choice, whoever did it that way.

In any case, you should re-test Firefox or Chrome, and see
what the latest interpreter is capable of. The above configuration
setting hints at capabilities that are present.

It is enabled (by default).
Interesting! This is news to me.

Ok, trying.
(Following my own notes from 2024-01-17). You can test it with:
<https://www.fema.gov/flood-insurance/find-form/policyholders>
then search for "Proof of Loss - Building & Contents" and click "Download Document" in that paragraph.
I have it downloaded years ago as fema_fi-proof-of-loss-building-and-contents-policyholder-prepared-form-ff-206-fy-21-108.pdf
Search for "amount claimed". Fill in the two boxes prior to it. The third box should have the total.
It does not.

This link has sample PDFs you can try. Some work in my FF (SimpleFormCalculations.pdf), most don't or do so partially (JSPopupCalendar).

Yes, weird behavior. "Partially working", which is the same as
"not fit for purpose". The output calculation is twisted 90 degrees.

Wow! I did not try that one. Weird!
So, support started with version 90. I have 128 ESR. So, maybe in five years more?
I recogn it is a difficult target, adobe doesn't have a track record of adhering to standards. Maybe this is not even a published standard.

I tried Acrobat Reader on the ConditionalCalcScripts and it works.

That shows how far off Firefox is for this.

I installed
Name: AcroRdrDCx642500120531_MUI.exe
Size: 733004184 bytes (699 MiB)
SHA256: 1D360E84BEA704D157846EFA3D197CEAE38646E9690CB211885F1F47791BF7D8
in a Win10 VM.
In the upper left Menu hamburger, the General choice, down near the
bottom, has three tick boxes that could affect the number of "challenges" delivered to the user. But the program still screws around like it
was Talky Toaster, annoying the hell out of me.
And every time it updates itself, you know what's going to happen to
those tick boxes :-/
I guess when you're Adobe, you just can't have few enough customers,
but, you'll keep trying.
