🔐 What Is Trezor Bridge?

Essentially, it replaces the deprecated browser extensions (like the old Trezor Chrome extension), enabling functionality across modern browsers, such as Chrome, Firefox, Brave, and Edge web-bridge-browser.gorgias.help+11portal-trxrbridge.gorgias.help+11bridgetrezor.m-pages.com+11.
