eBay is port scanning your system when you load the webpage


First off, I’ve to agree with @Yuliya right here. Running uBlock Origin or Nano Adblocker in medium mode is adequate to eliminate monitoring, there is no want for one more software that might be thought-about a redundancy.

As for your query, I’d prefer to defer the reply to the developer of Privacy Badger, which is IMHO wonderful and truthful:


Privacy Badger has a self-learning algorithm that can develop into fairly good over time in figuring out and completely blocking trackers. Privacy Possum is based mostly on the premise of feeding trackers pretend values. Both strategies are able to restoring your privateness, they’re simply two completely different approaches. But then once more, operating uBlock Origin with most / all lists enabled and in medium mode suffices, newly found trackers are being added to the lists fairly shortly.

For you or anybody else who is , a full disclosure of my Brave setup:

1. Why use Brave as an alternative of Chrome, or commonplace Chromium?

Essentially, it’s not calling house to the mothership and has sane privateness defaults on the code degree already, extra information right here: https://github.com/brave/brave-browser/wiki/Deviations-from-Chromium-(features-we-disable-or-remove)

2. My settings in Brave itself:

– All adblock lists enabled.
– HTTPS Everywhere enabled.
– All cross-site cookies blocked (blocking all cookies breaks too many issues, particularly login types).
– All cross-site fingerprinting makes an attempt blocked (blocking all fingerprinting breaks e.g. the eBay login type, ironic contemplating the article this submit seems below).
– Whitelisting social media login types disabled (maintain that enabled if you use Facebook / Twitter / Linkedin / Google accounts)
– Hangouts / IPFS Companion / Media Router / NetTorlease disabled.
– Tor Window enabled.
– Widevine – relies upon, if you are utilizing business streaming providers in your browser, depart it enabled, in any other case disable it.
– URL autocomplete – disabled
– WebRTC – Disable Non-Proxied UDP – https://github.com/brave/brave-browser/wiki/WebRTC-Custom-Settings
– Brave telemetry / distant debugging – disabled
– Push notifications – disabled
– Google SafeBrowsing – disabled
– Allow websites to examine for cost strategies – disabled
– I even have set the browser to delete cookies and cache upon closing in its web site settings.

three. Chromium flags I’ve set in Brave:

– Reduce default ‘referer’ header granularity. – Enabled. – chrome://flags/#reduced-referrer-granularity
– Prefetch request properties are up to date to be privacy-preserving – Enabled. – chrome://flags/#prefetch-privacy-changes
– Secure DNS lookups (DNS over HTTPS, DoH) – Disabled. – chrome://flags/#dns-over-https
My motive for disabling this you can discover right here: https://blog.powerdns.com/2019/09/25/centralised-doh-is-bad-for-privacy-in-2019-and-beyond/

four. Extensions I run in Brave:

– Nano Adblocker (fork of uBlock Origin, I take advantage of it due to its default integration with Nano Defender) – for customized aspect blocking and extra filter lists, I extremely suggest so as to add an anti-cryptomining blocklist as nicely, since uBO / Nano Adblocker appear to be a bit missing in that division.

– Nano Defender, to hide the presence of Nano Adblocker

– LocalCDN (fork of Decentraleyes, extra lively now and helps extra libraries), to dam connections to CDNs

– Cookie AutoDelete, as a result of there is no motive to maintain cookies after the associated tab is closed, I’ve set this to delete upon area change; additionally clears IndexedDB storage

– ClearURLs, to eliminate monitoring parameters in URLs and to stop eTag monitoring, additionally prevents monitoring by way of the History API

I’ve no bother on any web site in any way with this setup. I’ve solely encountered one downside. In YouTube, autoplay appears to be realized by way of a cookie, so if you have flip autoplay off after which shut all YouTube tabs, Cookie AutoDelete will delete this cookie and autoplay will get re-enabled once more. But concern not, I discovered an answer: Enhancer for YouTube, developed by MaximeRF, has an choice in its settings that permits you to disable YouTube autoplay by way of a separate script run by the extension, this is how I turned off YouTube autoplay for good, even when Cookie AutoDelete is operating. Apart from that, no issues.

The one weak spot that also stays is being weak to new (not but blacklisted) fingerprinting scripts, however the Brave workforce is already engaged on Fingerprinting Randomization, so there is that. I additionally suggest establishing a Pi-Hole in your house irrespective of which browser you use.

A bit prolonged, however I hope this helps.
