I tried it for the first time a few weeks ago (I never do web/HTML stuff). Seamonkey Composer crashed when I tried inserting a <video> element.

According to the release notes (http://www.seamonkey-project.org/releases/seamonkey2.53.1/) it is mainly features removal and breakage :-/ The least one can cay is that they are not chatty about the positive changes and features those underlying changes may have brought.
And yes, I was mildly disappointed when I downloaded and ran this as I saw no real visual difference or changes to the UI and preferences.
So I guess Composer is not much of an option for "real" work these days. Still cool to see an alternative browser out there that's at least mostly capable of handling the "modern" web...
I don't really use it often but I love that it still comes with Composer for WYSIWYG html. It's been a while but when I used it a lot about 5-7 years ago it wrote really clean, standard compliant html which made it great for quickly prototyping look and feel before diving into writing any code for new pages/sites.
