Can set text in textbox on Chrome, IE but not on Firefox

I’m trying to setText to a textbox but I can’t make it works on Firefox. It work flawlessly on Chrome and IE.
The test step does pass and indicate it successfully write in the textbox but there’s nothing except the textbox got the focus.

I tried sendkeys(), removing any text in the textbox before, set Focus() to the textbox before writing and clicking inside the textbox before setText() or sendkeys()

Here’s a screenshot from the HTML

I solved it.
Solution : Using Execute Javascript keyword, I do : “document.getElementById(“inputId”).value=[text];”
