19 I'm using the combination of these browser add-ons available for
20 Firefox and Chromium:
22 uBlock Origin
23 uMatrix
24 EFF Privacy Badger
26 uBlock Origin is an ad blocker.
27 uMatrix is similar to NoScript but a lot more flexible and easier to
28 use, and comes with some hosts files (not copied to /etc/hosts).
29 And Privacy Badger blocks domains, JavaScripts, cookies etc. that are
30 used to create a profile of yours.
32 Those three are doing quite a good job from what I can tell. And surfing
33 on a Raspberry Pi 3 is also a lot better with these.
35 That said, it's not only ad servers which cause a massive CPU load, it's
36 also badly designed and overloaded websites which contain a lot of
37 JavaScript and load content from several other servers, particularly
38 from JavaScript hosts and CDNs.
