Switchboard of uMatrix

uMatrix is a Firefox extension that can be used to control exactly what network requests are made by the browser and thus what is loaded in the requested webpage. It is of similar use as ad-blockers (like AdBlock) or script blockers (NoScript) or other blockers like uBlock. But, uMatrix is more fine-grained and a bit more complicated but gives you a lot more idea of what a webpage is trying to load and if you would want to allow that. uMatrix is a fork and improvement over an earlier addon called HTTP Switchboard.
