    • Bug: 1306801 Remove Necko IPC security 

  • Tim Huang[:timhuang]

    • Bug: 1922193 Sending multiple (unknown) cookies with same name 

• Round Table

  • [valentin] Related to 1910991 above, I tried using wireshark to see the decoded requests.

    • ECH is enabled on Cloudlare, which means Wireshark is unable to decode the packets. Yaroslav Rosomakho from zscaler has patches for NSS and Wireshark - will submit them next week. Until then network.dns.native_https_query:false and network.trr.mode:5 should avoid ECH
