Good Bear 1.0 Released: Firefox-Based Browser with Isolated Russian PKI Trust Container

Good Bear 1.0 is a Russian-language browser built on Firefox 156.0 that provides an isolated container for handling Russian PKI certificates without mixing trust contexts or user data with the standard browsing session. The release includes .deb packages for Ubuntu 24.04 LTS amd64 and Windows x64 installers, using Mozilla Public License 2.0 and reproducible build processes from pinned Firefox sources. Instead of globally importing root certificates, the browser performs secondary chain validation only inside a dedicated userContextId container with strict OriginAttributes isolation for caches, storage, and connections. Password autofill and sensitive session data are disabled in the container when separation cannot be guaranteed, and POST requests trigger explicit user choice before reopening in the isolated context. The interface shows both a persistent container marker and a separate RU indicator only when Russian PKI is actively used, along with detailed security panels explaining the trust source. Updates, crash reporting, and automatic MAR mechanisms are intentionally omitted to avoid creating unverified trust chains for the distribution itself.
