Hi

I would start by clearing the browsing history, but if this does not work for you, I would find Firefox in the Applications menu in the Android Settings app and clear cache (not data!).

I hope this helps.

How can I clear a cached 301 redirect in Firefox for Android version 79? I am using Firefox to test a website I am developing.

Clearing history did not work, but, I went into app info on the settings menu in Android and was able to clear it there. Now it works! Thanks.
