User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.72 Safari/537.36

Steps to reproduce:

My Rails page has form with hidden input to set HTTP submit method - put in this example.

Re-loading the page with location.reload() changes hidden input value - the form is not present on the page before reload.

• HTTP from the server is correct with put as a value for _method hidden input
• happens only in Firefox (tested on clean Mac version and WIndows version with some Extensions)
• full page reload solves the problem (not Control/Command + R)
• turning autocomplete for the form also solves the problem

Actual results:

After location.reload() value in hidden form input is changed.

Expected results:

Hidden form input shouldn't be autocompleted/changed by browser.

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Core & HTML' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

This can be worked around by tweaking the autocomplete preference .
