I upvoted the top two answers, because they are both correct.
To clarify, it should be either ... in another context?" or ...
in other contexts?
Both are correct and acceptable, but never "in other context?"

Example: 'The word "seaboard" can be used in the context of a coastline; it may also be used in (many) other contexts.'
When there's one, it's context, when more than one (or possibly so)
it's plural - contexts.
Using "any other context" or "another context" sounds to me like you are pre-suposing there is only one other, although it would not be very clear.

Of the two options you supplied, ... in other contexts? is correct.
Another option, ... in another context? is also correct, but whether you use it will depend on whether there are multiple "contexts" or just one, to consider.
Of course, "context" is singular, indicating only one; while "contexts" is plural, indicating many.
Thus, to say ...
in other context? would be incorrect, as "other" implies multiple, while "another" implies one.

I just asked about the phrase "Eastern Seaboard" in another question. I used the sentence: Is "seaboard" used in other contexts? I thought this didn't sound very good, so I changed it to: Is "seaboard" used in other context? Should context ever be pluralized? Or is it a mass noun?
Should I say "context" or "contexts"?

Since "context" is not a mass noun, it will take the plural -s. Alternatively, you could say "another context" instead of "other context". Context is not a mass noun, and takes the plural -s, so it is fine to say "contexts".

Context  is not a mass noun, and takes the plural  -s.  Of the two options given, "... in other contexts"   is correct.   The word contexts is a countable noun and should be pluralised. The term "contexts" is correct.
