PR_END_OF_FILE_ERROR in Firefox using latest 1.3.2 plugin with ss-local

[greenais]

Debian Bookworm x64
Same shadowsocks-libev + v2ray setup on both sides (server and client)

ss-local starts with no issue

$ ss-local -s "176.218.188.226" -p 2023 -l 1080 -k "password" -m "chacha20-ietf-poly1305" --plugin "/etc/shadowsocks-libev/v2ray-plugin"  -v

but in FF I get PR_END_OF_FILE_ERROR - how to narrow issue?

Meanwhile in quite old GUI client Shadowsocks-Electron-1.2.3 everything works with same server setup.
Client has v2ray incorporated as stated.
