Adblock Plus now lets users block tracking from social media buttons in Chrome and Firefox, is considering whitelist options for certain social sites

Context & Ripple Effects
Adblock Plus has been steadily widening its filters beyond ads: in 2017 it shipped a filter against covert crypto-mining scripts, and this update extends the same logic to the tracking pixels behind social media share and like buttons in Chrome and Firefox. The reported openness to whitelisting certain social sites echoes its long-standing acceptable-ads posture — filtering as a negotiable default rather than an absolute block.
The move lands in a market where platforms actively fight back: Facebook responded to earlier blocker pressure by changing the signifiers used to detect its desktop ads, a template for how social networks evade client-side filters. Meanwhile Google was already reported to be building ad-blocking into Chrome itself, meaning the browser layer is becoming a filtering battleground.
First-order effects
- Adblock Plus users in Chrome and Firefox stop leaking social-button tracking data to the platforms behind those buttons, cutting off a passive data stream that required no click.
- Sites embedding share buttons lose retargeting and attribution signal from this user base, while the buttons themselves keep working — the cost falls on the networks, not the publishers' page functionality.
Second-order effects
- Facebook and comparable platforms have already shown the playbook — Facebook's signifier changes to bypass desktop blockers — so expect tracking to migrate toward server-side and logged-in channels that client-side filter lists can't see.
- Google's reported plans to build ad-blocking into Chrome compress Adblock Plus's differentiation at the browser layer, pushing extension makers toward privacy features the browser doesn't yet ship.
Third-order effects
- The pattern — extensions blocking covert tracking, then browsers absorbing the job, as Firefox later did with stripping Meta, HubSpot, and Marketo trackers from URLs — points to tracking protection becoming a default browser feature rather than an add-on.
- As client-side blocking tightens, social platforms' structural response is login-walled identity: tracking that follows the authenticated user rather than the page, which regulators and filter lists are poorly positioned to touch.
The trend: Ad-blocking tools are evolving from blocking ads to blocking covert tracking, with browser vendors gradually absorbing the function and platforms shifting tracking into logged-in, server-side channels.
