I am using a mac 2018 Intel. When I upgraded from Sequoia 15.3 to 15.4 Firefox quit working. I turned the firewall off and it worked for awhile. But has not continued. I found this reference on-line. https://support.mozilla.org/en-US/kb/firefox-blocked-macos-15-sequoia-firewall-what-you So I am assuming some additional information may be available. Anything new on this issue. I have been a Firefox user for multiple years. It is my primary browser. Thank you Bill Parks wp12@totbaw.com
