I had typed up a message to post on Mozilla Support, to ask for help with Firefox. When I opted to share troubleshooting information on it, it could not do so automatically, which is problematic enough. When I clicked on the "try these manual steps" link, the browser went to another page. When I hit the back button to return to what I had typed, to add the troubleshooting information to the post, there was none of the text there anymore.
This is not great. Either save a draft of what's typed in when navigating to another page, or make that link open in a new tab, or in a modal popup, or something. Don't obliterate what the user typed and make them start over from scratch.
