I don't use Android swipe gestures but I presume they would work in FF too. Nonetheless, we should avoid posting "it works in Chrome" as an answer to anything.
I have a deep-seated hatred for Chrome-only devs - not least of which is because it has contributed to the situation we are in, where Google is taking the "my way or the highway" approach to Chrome and adblockers, Android is locking us out of sideloaded apps, etc. Test at least in Chromium and FF as a bare minimum. Submit condescending bug reports to those stupid react components that break entire websites and nobody bothers to check, etc.
Except there's literally nothing a web page should be able to do to stop your back gestures from working, that's an OS and browser responsibility. If it isn't working it's the OS and/or browser's fault.
