 Just like the scripts loaded by normal web pages, content scripts can read and modify the content of their pages using the standard [Web APIs](/en-US/docs/Web/API). However, they can only do this when [host permissions to the web page's origin have been granted](#permissions).

+> [!NOTE] Some specific Web APIs are restricted to [secure contexts](/en-US/docs/Web/Security/Secure_Contexts), which also applies to content scripts running in these contexts. Except for {{domxref("PointerEvent.getCoalescedEvents()")}}, which can be called from content scripts in insecure contexts in Firefox.
 
 Content scripts can only access [a small subset of the WebExtension APIs](#webextension_apis), but they can [communicate with background scripts](#communicating_with_background_scripts) using a messaging system, and thereby indirectly access the WebExtension APIs.

 The **`getCoalescedEvents()`** method of the {{domxref("PointerEvent")}} interface returns a sequence of `PointerEvent` instances that were coalesced (merged) into a single {{domxref('Element/pointermove_event', 'pointermove')}} or {{domxref('Element/pointerrawupdate_event', 'pointerrawupdate')}} event.
 Instead of a stream of many {{domxref('Element/pointermove_event', 'pointermove')}} events, user agents coalesce multiple updates into a single event.
