history.onVisitRemoved

Fired when a page is removed completely from the browser history.

If all visits to a single page are removed (for example, using history.deleteUrl), then this event is fired once.
If a range of visits is removed (for example, using history.deleteRange or a browser feature like "Clear Recent History"), then it is fired once for each page whose visits all fall within the cleared range.
If the browser's entire history is cleared (for example, using history.deleteAll), then it is fired only once.

Syntax

browser.history.onVisitRemoved.addListener(listener)
browser.history.onVisitRemoved.removeListener(listener)
browser.history.onVisitRemoved.hasListener(listener)

Events have three functions:

addListener(callback): Adds a listener to this event.
removeListener(listener): Stop listening to this event. The listener argument is the listener to remove.
hasListener(listener): Check whether listener is registered for this event. Returns true if it is listening, false otherwise.

Parameters

callback

Function that will be called when this event occurs. The function will be passed the following argument:

removed

object. Details of the removal. This is an object containing two properties: a boolean allHistory and an array urls.

If this event is firing because all history was cleared, allHistory will be true and urls will be an empty array.
Otherwise, allHistory will be false and urls will contain one item, which is the URL of the removed page.
