Hubspot form on Firefox


I have a bug with my Hubspot form that only happens on the last version of Firefox 69.0.3:

This is the website:
The form appears when you click on Pre-order now.

Read-only link: Webflow - Nectar

I try to determine if the bug is from Hubspot or if I can do something about it in Webflow…
Thank you for your help!

Better late than never.

Add this inside the head of the page’s HTML:

.hs-form-iframe { width: 100%!important; }

Fixed it for us.
