Notes

• Due to limitations involving extension signing and installation on Nix, it is not recommended that this is included in a NixOS system flake (or configuration.nix). There is nothing stopping you from doing so, but the point is somewhat defeated by the necessary manual steps of installing the extension and native messaging host. Theoretically, home-manager can probably overcome the issues, but I do not and will not use home-manager. This flake is, however, a starting point for a completely declarative flake or derivation
• The mount path can only be changed by editing flake.nix. This is a limitation in the original tabfs browser extension code. Technically tabfs.c reads the mount path from $TABFS_MOUNT_DIR but this is not passed from the native messaging host plugin, meaning it is not configurable. Without the environment variable, it defaults to mnt in the working directory of the launching application. On Nix, this is most likely a read-only directory. My solution was to wrap tabfs with TABFS_MOUNT_DIR set to /run/user/$(id -u)/tabfs in the Nix derivation.
