Does CCleaner support SeaMonkey 2.2?

Does CCleaner support SeaMonkey 2.2? That's the latest version of SeaMonkey released a few days ago. I have it installed as my default browser on XP Home SP3.

According to http://www.piriform.com/ccleaner/features, SeaMonkey is supported, however there's no mention of it in my CCleaner GUI. Why not? (I only see Firefox mentioned therein.)

Clarification appreciated. Thanks!

I believe that seamonkey is included in Mozilla/Firefox (but don't use it so can't be sure)
