Hi, Euranna —
Sorry for the delay in responding.
Yes, of course it's OK. I'm sure Our Lord is pleased when you participate in such activities. Online Mass, however, is no replacement for attending in person and does not fulfill your obligation to attend liturgy on Sundays and holy days. If you are unable to (or some other grave reason exists), you are excused.
Theologically, it's not resolved whether online adoration has the same fruits as in-person adoration. But certainly, it is meritorious.
