Firefox usually will retain form data -- if the site allows Firefox to cache the page.

To check the caching instructions, you can open the web console (Ctrl+Shift+k) and then load the form in that tab. To clear the cache and pull fresh from the server, use Ctrl+Shift+r. Then click the URL in the web console to view the headers, scroll down to Response Headers, and check Cache-Control. Anything like no-store that would bar Firefox from keeping the form data in cache?

And/or, can you provide a link to a form that isn't working the way you want?

the above you have mentioned doesn't seems to solve my issue

Here is the link of the form. Live form

When you enter wrong captcha code in firefox after reloading the page it doesn't retains the value. I have used the cache control but no success.

Please let me know if you can help.

Thank you

The server is sending "no-store" with the page, so Firefox does not store the form after you leave the page. (See attached screen shot.)

By the way, when I intentionally entered the CAPTCHA wrong, I got an alert and was able to correct it before trying to submit the form. I'm not sure of the steps you are using to create the problem.
