It’s not clear how you have tried to use ligatures, and which ligatures using which font. Primarily, ligatures are used via OpenType features in fonts that support them, and I would not expect e-book readers to be able to deal with this (you would use font-feature-settings in CSS). Inserting a zero-width joiner is a character-level request for applying ligature behavior when available, but probably ignored by most e-book software.

There is however a clumsy way, using ligature characters such as U+FB01 LATIN SMALL LIGATURE FI, which you can enter in XHTML as ﬁ (or as such, character ﬁ). There is a small set of such characters, but they work reliably in modern software provided that the font being used contains that character, in its correct position. (Many fonts contain such ligatures but possibly in wrong code positions.)
