I was doing Late Answers review when I bumped into this question:
How do I export saved passwords from my firefox password manager?
The new user basically repeated a previously posted answer. They used a longer URL that ultimately leads to the same website and added another link that points to a web page that was created today. It actually covers the topic (it explains how the add-on work step-by-step), but I kind of feel like it's just posted to promote their website and not to improve AskUbuntu.
Should you flag such attempts as spam?
