The problem with converting to epub for these html books is that I want to take advantage of firefox addons (such as perapera chinese popup dictionary) since I'm using these books to help with language learning. I tried using epubreader but the other addons do not play nicely wih it.
Anyway my roundabout solution is that I've converted them to txt files and I'm using the
fineBook addon to bookmark my progress. It would be nice to have the fancy styling that html files bring, but using txt isn't the end of the world.
My use case is pretty limited so I don't expect much developer interest I guess. It'd be nice if there was a firefox addon to handle htmlz. Thanks for the help.
