	Name	Description	Size	Coverage
	BackgroundPageThumbs.sys.mjs	Asynchronously captures a thumbnail of the given URL. The page is loaded anonymously, and plug-ins are disabled. @param url The URL to capture. @param {object} [options] An optional object that configures the capture. @param {Function} [options.onDone] A function that will be asynchronously called when the capture is complete or times out. It's called as onDone(url), where `url` is the captured URL. @param {number} [options.timeout] The capture will time out after this many milliseconds have elapsed after the capture has progressed to the head of the queue and started. Defaults to 30000 (30 seconds). @param {boolean} [options.isImage] If true, backgroundPageThumbsContent will attempt to render the url directly to canvas. Note that images will mostly get detected and rendered as such anyway, but this will ensure it. @param {number} [options.targetWidth] The target width when capturing an image. @param {string} [options.backgroundColor] The background colour when capturing an image. @param {boolean} [options.dontStore] If set to true, the image blob won't be stored to disk, an object will instead be passed as third argument to onDone: ``` { data: an ArrayBuffer containing the data contentType: the data content-type originalUrl: the originally requested url currentUrl: the final url after redirects } ``` @param {string} [options.contentType] Can be set to an image contentType for the capture, defaults to PageThumbs.contentType. @param {number} [options.settleWaitTime] Milliseconds to wait after the page reports loaded before capturing, to allow for in-page redirects. Defaults to 2500. Set to 0 when capturing a direct image URL where no settle is needed.	25514	89 %
