An example method of managing ads in a browser application includes receiving a request to load a webpage referenced by a uniform resource locator (URL). The webpage includes a set of ads, and each ad of the set of ads includes one or more ad resources. The method also includes searching a browser cache for a set of cached ads associated with the URL. The browser application caches ads included in one or more webpages into the browser cache. The method further includes composing an ads page including at least one cached ad of the set of cached ads and displaying the ads page on a client device.
