OpenBSD -current, firefox-147.0.4

After package update I discovered that firefox stopped playing videos.
I found some screaming messages in firefox output.

firefox: /etc/firefox/pledge.rdd: pledge(stdio rpath tmppath recvfd
 sendfd unix) failed: Invalid argument
firefox: /etc/firefox/pledge.utility: pledge(stdio tmppath rpath recvfd
 sendfd prot_exec unix) failed: Invalid argument
