[xExtension-YouTube] Loop loading entries

[Alwaysin]

With this extension enabled, when displaying a Youtube feed, the page takes way more time to finish rendering completely than it takes when there are no Youtube feed entries. When I uncheck "Use lazy load mode to load pictures" in reading configuration and I go back on a Youtube feed, it loads quickly BUT there are so many requests going on after a little while initiated by youtube.com domain and others (doubleclick trying to load ads, play store, etc).

E.g. on a page with 83 entries, after 3 minutes (it was still continuing): 26k errors and 30k+ warning in console log ^^'
