All Things Chrome: the Complete Guide to Cookies, Extension Safety, and Privacy Fixes
By Marcus Vance
Browser extensions run with elevated permissions inside your web environment. Many add-ons require the right to "read and change all your data on all websites you visit." While an extension might begin as a harmless color picker or document converter, developers regularly sell abandoned extensions to shady advertising agencies that slip malicious tracking payloads into subsequent updates.
Protecting yourself requires a methodical extension security audit. Type chrome://extensions into your address bar. Scrutinize every add-on currently enabled on your workstation. If you see tools you haven't opened in two weeks, remove them immediately.
Next, restrict access boundaries. Rather than allowing extensions to inspect all pages universally, click Details on each essential tool and adjust Site access. Switch the default from "On all sites" to On click or On specific sites. This simple adjustment prevents background extensions from snooping on authenticated corporate portals, crypto wallets, and webmail accounts.
