“This browser extension stops Facebook social plugins—including those within iFrames—from running on sites other than Facebook itself. This includes ‘Like’ buttons, ‘Recommended’ lists, and should also stop any Facebook scripts from tracking your browsing history.”
Sites using Facebook’s ‘social plugins’ have been chewing up memory in my Safari (stemming from, I think, based on looking at the ‘Activity’ window, a blocked request returning an error and being requested over and over again). I’m still not sure what the issue was (AdBlock or Facebook Cleaner extension conflict, probably?), but with this extension the plugins don’t have a chance to load in the first place, which is fine because I never use them and I think they’re worthless and annoying.
This bookmarklet makes reading things on the web very simple and thus enjoyable by removing all of the often-useless and often-flashing worthlessness surrounding the content.
