YOUR extensions leak clues about you, so Malwarebytes says Browser Guard has been enhanced to stay private. The piece notes that advertisers can infer what kind of user you are from the extensions you have installed, and that the risk isn’t limited to advertisers—scammers, identity thieves and stalkers could exploit the data too.
It points to recent reports via BleepingComputer that LinkedIn was scanning visitors for more than 6,000 Chrome extensions, linking that data to profiles, and to a breach at Gravy Analytics exposing highly sensitive information that put millions of people at risk. The article explains how Browser Guard tries to reduce exposure by using browser storage APIs and dynamic URLs, with the use_dynamic_url flag mentioned as a way to create a new, session-specific identifier.
It also notes that the behavior of dynamic URLs differs by browser: off by default in Chrome and Edge, but Firefox enables it by default with no option to disable. The author, Cameron Eckelberry, frames these changes as making Browser Guard harder to fingerprint, according to Malwarebytes. 8 April 2026.
