Hey! I’ve looked into this before — unfortunately, most Gmail extensions only work on desktop, so there’s not really a way to reverse threads directly on an iPad.

The easiest workaround is to turn off conversation view in the Gmail app. That way, emails show individually with the newest on top. You could also try a different mail app like Outlook or Spark; they usually let you sort emails the way you want.

Firefox on iOS/iPadOS is using webkit as the base as to why there are no extensions like there are for desktop and Android Firefox. https://support.mozilla.org/en-US/kb/add-ons-firefox-ios
