Is Quest PDF safe?
Quest PDF sets itself as the default search provider and sends search and suggestion terms to QuestPDF and Yahoo endpoints.
Quest PDF declares a default browser search provider that routes searches through Yahoo with extension-specific parameters. Its suggestion and omnibox handlers also send typed search queries to suggesting.questpdfapp.com for completion results.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 2 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
