find.highlightResults()

Highlights the results of a previous call to find.find().

When an extension calls find(), the matches are not highlighted automatically, but they are stored by the browser. Call highlightResults() to highlight them.

Note that the stored results are global across all extensions, so for example, if extension A calls find("apple"), then extension B calls find("banana"), then if extension A calls highlightResults(), the results for "banana" will be highlighted.

Syntax

browser.find.highlightResults(
  options // optional object
)
