Tor Browser
An anonymizing web browser developed by the Tor Project. It standardizes browser-identifying characteristics across all users—including window dimensions, font subsets, and Canvas rendering output—making individual users difficult to distinguish from one another, and is among the most privacy-protective browsers available.
Timeline (last 90 days)
Tor Browser reduces identifiability by standardizing characteristics so that all users present as similar as possible, causing individual users to be lost in the crowd.
The core idea behind Tor Browser's feature standardization strategy derives from the concept of anonymity sets, where a user's identifiability depends on the number of users with exactly the same characteristics.
Adding an Onion-Location HTTP response header to a website's headers enables Tor Browser users to automatically detect and be redirected to the .onion version; this practice has been adopted by institutions such as Facebook and The New York Times.
Ordinary users need to install Tor Browser to access .onion sites, which is a significant barrier for services targeting the general public.
