Modern Chrome Web Extension and Firefox Browser Addon to easily clean selected cache items specific sites or the whole browser with a single key press, from the right-click context menu or via the toolbar icon popup.

Firefox does not have an API to clear cache storage, the cache created by service workers. Furthermore, it has no option to bypass the service worker for network when testing. This extension resolves that issue by using a custom function to clear Cache Storage when clearing site cache plus has an option automatically reload the page after clearing the cache. Now after making a change to a site with a service worker, all you have to do is press F4 (default keybind to clear cache) to clear the cache and refresh the site. Additionally, the browsing data API differs on Firefox and Chrome so logic was added to allow the extension to run on both browsers.
