Installing Ghostery, Privacy Badger and adblocker makes a world of difference in terms of how fast page loads are for me. Ads are not just annoying, they slow the web down considerably and make the mobile experience terrible.
I just use NoScript, and it's astonishing just how many sources some pages use. Just looking at the block list in NoScript for an online-newspaper sort of site, and there'll usually be about 20 javascript sources.
Why would you use adblocker/ublock and 2 other extensions which are no more than a filter lists for adblocker/ublock?
Privacy badger is a little different, afaik it doesn't use lists.
It says in the FAQ section of the official site that the main difference between it and other blocking extensions is ease of use aka lack of setup.
It also claims it's based on adblock code. So it's just adblock with lists preset?
Indeed a little difference if you're able to setup adblock-like extension. And if we're discussing performance, you don't want an extension for every list out there.
Ghostery sold out, they sell your metadata to 3rd parties. Try uMatrix instead. It is as powerful as NoScript, but easier to use. For adblocker, consider uBlock Origin. Better performance, and didn't sell out.
