Please note that SeaMonkey 22.214.171.124 has been released.
For transparency and fyi, this release was delayed by a few days due to some technical difficulties (mine… started the release process last week but failed a few times over the weekend).
That stated, the updates are up and confirmed running so your 2.53.5+ systems should be updating to 126.96.36.199.
Please check out  and/or .

Thanks. I used the internal updaters in 64-bit W10 Pro, macOS Big Sur v11.6, and very old 64-bit Debian Jessie v8. 😀
