// 2020-10-25 Added support for some of the searx sites (provided they have 'searx' in the domain).
// 2020-04-21 Re-enabled for Ecosia and StartPage, bypass CSP by fetching the images using GM_xmlhttpRequest.
// 2020-02-02 Reenabled Google again, because Google has stopped showing favicons.
// 2020-01-22 Disabled Google, because Google is now displaying favicons itself.
// 2020-01-22 Disabled Ecosia, because their CSP is blocking images
// 2018-10-14 Added support for ecosia.org!
// 2018-10-14 Disabled startpage.com, because their CSP has blocked favicons from loading.
// 2018-07-31 Dropped support for news.google.com, because it is now linking to local URLs, instead of to external websites.
// TODO: The relative positioning of the icon appears a bit off for sub-links of the main result.
// DONE: Provided more options where to place favicon: by the link or by the
// url, before or after, inside or outside the link. However in my opinion
// they all suck except the default. ;)
// Broken images would be messy, but Firefox seems to hide them after a while
// anyway. We do still see the gap from the image's padding though!
// It might be desirable to check each image actually exists/loads, or remove it.
// Is that possible, without making an http request ourselves?
// Third-party host URL detection is implemented leniently, and accordingly
// hostname extraction implemented aggressively, which results in favicons
// being given to unexpected things like bookmarklets which contain a site url.
