Firefox – How to disable spell checking in Firefox for a specific website/domain

firefoxspell-check

I want spell checking enabled on Firefox except in a few websites.

How can I permanently disable spell checking in a specific website or a domain, e.g. foo.xxx?

I know I can right-click and remove the check mark from "Check Spelling" but that is temporary, I want something that saves the setting for that particular website or text field.

If it's a website you have control over, you could set the spellcheck attribute on the input tags.

<input type="text" spellcheck="false" />

I just used this attribute on a text field where I asked the user to enter a work order number that included letters and numbers. (Definitely not a dictionary word.) Worked perfectly.
