I see a similar crash (with firefox-132 from 2025Q1). The
crash is caused by:


./gfx/ots/src/name.cc:17

// We disallow characters outside the URI spec "unreserved characters"
// set; any chars outside this set will be replaced by underscore.
bool AllowedInPsName(char c) {
  return isalnum(c) || std::strchr("-._~", c);
}
