Software Update: Tor Browser 11.0.3

Version 11.0.3 of Tor Browser has been released. Tor stands for The Onion Router and is a network that can be used to surf the Internet fairly anonymously. All users’ tcp traffic is routed through various Tor routers, after which it is virtually impossible for the receiver to find out who the original sender was. This information is still present within the Tor network, so that answers, of course also via the system of routers, eventually arrive at the right place. Version 11 is based on Firefox ESR 91, where version 10 was still ESR 78. The changelog for this release looks like this:
