An open security extension for browsers that starts from a conservative trust level for unclassified sites and lets the user decide which ones may run scripts. Permissions can be set per site, and the same component ships inside the Tor Browser. Version 13.6.36.

An open source browser project maintained mainly by Google, with core code under a permissive licence and test oriented builds published alongside release channels. Design documents, architecture notes and test material sit next to the source, across Windows, macOS and Linux.

For most people the first browser they install is still Google Chrome.

Sign in and bookmarks, passwords and settings follow you to every device, while the old extension format finally left the store at the end of August 2026.
