These are just one native speaker’s impressions, so take them with a grain of salt.
Your first two examples, to me, scan as being about abstract concepts; respectively: the emotion/quality of curiosity and the property of being in context.
This quora result indicates that it’s a quality of “definiteness” that indicates when articles get dropped (maybe as a second language learner you’re likely to already have this as knowledge, but find it difficult to intuit).
In those examples, the meaning doesn’t rely on pointing at two specific “curiosity” and “context” objects that have to be precisely designated, it relies on set phrases “out of curiosity” and “in context” that respectively describe an unmentioned action or object.
I think the article in the last example is dropped for a completely different reason. The “definiteness” argument doesn’t apply, but my instinct is that this is simple terseness in the communication from UI to user. Describing every UI element with precise language would result in web pages that resemble legal documents.
