Huh, I don't have Pull to Refresh under Settings > Customise > Gestures. I wish I did.

I only have "Scroll to hide toolbar" and "Swipe toolbar sideways to switch tabs"

This is in Firefox 108.1.0 which is the latest.

I know you can mess with Nightly to allow other addons but I don't really like using nightly to be honest. This feature should really be in the mainline too.
