FreeNet Hub 4.3.7 Linux R19 browser fix
FreeNet Hub 4.3.7 — Linux browser action patch R19.
- Linux: explicit unprotected system-browser button; tunneled browser remains fail-closed until connection health is verified.
- Linux: verifies Firefox process launch before reporting success; preserves useful error feedback.
- Linux package: FreeNetHub_4.2.0_Linux_R19.zip (4.2.0-linux.19-r46).
- Windows: original FreeNetHub_4.3.7_R51_Setup.exe, byte-for-byte unchanged (SHA256 8283803146e1625a31f0223487a63c05d7b7d9c3d8b59d1a7432d14ab9d4ff11).
- Linux R19 fresh install and R18 upgrade tested in isolated HOME with locally verified pinned runtimes; native Ubuntu 26.04 isolated Firefox launch verified.
- VPN/node functionality still depends on available live upstreams; this patch does not claim to resolve blocked network paths.
