Protecting against a tracking parameter in a web link. In one embodiment, a method may include receiving an input URL during a browser navigation session on a user device, the input URL including parameters, determining that the parameters include a tracking parameter, pausing the browser navigation session on the user device, launching the input URL in a headless browser that operates in an isolated environment that simulates one or more features of the user device, landing on a destination web page in the isolated environment, identifying a URL of the destination web page as a destination URL, and resuming the browser navigation session on the user device by replacing the input URL, which includes the tracking parameter, with the destination URL, which does not include the tracking parameter, in order to protect the user device from the tracking parameter.
