autofill doesn't work

Hello, First, check if auto fill is enabled. Click the menu button (3 horizontal lines) > settings > privacy & security. Scroll down to Addresses and more and check the box for Save and fill addresses. Go to passwords in the left menu, click the menu icon, and make sure login saving and filling is active. Next, (if applicable), go to settings>Privacy & Security, then under history set Firefox to Use custom settings for history. Lastly, clear your recent cookies, cache, and form history to remove corrupted local entries that block autofill. Note that cookies may sign you out of some websites and history will delete search suggestions. Next, check locale config. Go to about:config, then search for '''browser.search.region''' and make sure it is set to a supported region like US. After that, restart Firefox.
