If you use forums, particularly ones without an inline BBCode editor, this is essential, and, as a bonus, it's not something you can get in Google Chrome -- that is, this extension offers Firefox features that are beyond Chrome's ability to provide via extensions. Also, even if your forum of choice has an inline editor, maybe it just has bold and italic, link and picture; they seldom support spoiler tags and strike-out. You can add those manually. Also good for Reddit formatting (if you have RES, you can't post links, because the RES developer hasn't figured out how to add that feature, although it's very easy to add here).
