As you figured out, innread.com is not a site supported by FFF.

FYI, FFF is supporting fewer translation / novel site for a few different reasons:
- They tend to be more complex, to the point of being difficult or even effectively impossible to support in FFF.
- I don't read these sites and don't have any interest in supporting them. There hasn't been a lot of interest from other developers either, in part because of 3:
- I don't want to include sites that carry copyrighted material that might potentially cause legal issues. Here's an old discussion about it.
