I tried filling out a Contact form on a website here: https://www.klineind.com/contact/ using Firefox and after submitting it, I got the message, "Sorry, for technical reasons you can't submit your query from this browser. Please try using a different browser or computer." So I started over again using Google Chrome and the form was successfully submitted! I have screenshots of both Firefox and Chrome after the submission but I cannot attach them here, it appears. For better troubleshooting, I suggest that screenshots be allowed to be attached. I have recently had some issues with Firefox's compatibility and which hopefully will be addressed. Thank you.
