i recently discovered that the Canadian government depends on this for some fillable forms, because it shows a message at the top that says "JavaScript is disabled" and all the boxes show errors. i couldn't get it to work on Linux and had to dust off a Windows machine (and it still didn't work in firefox, it needed acrobat reader).
I have faced this exact problem with Canadian govt forms.
Evince doesn't support them. They are so specific about only adobe acrobat to fill out the forms.
I can open them in firefox but can't update them properly
The only option is to use my barely hanging on 10-yr old windows machine.
Let's hope that eventually they move on to a simpler web form.
(below is not serious)
I would advise people against using this in production though because it's still missing some critical features. For example:
1. The Javascript stops working when printed to physical paper. The resulting paper just has a static image and the controls no longer work.
2. It doesn't work properly in Evince. It just shows an error "The document contains only empty pages"
