Problems with Slackware-15.0, Firefox, and QUIC (HTTP3) sites?
by ljb643 from LinuxQuestions.org on (#6JFAT)
This might have started when Slackware-15 upgraded to firefox-115.7.0ESR. Or maybe not. One specific financial site no longer works - pages lock up for several minutes, sometimes they eventually recover, sometimes stopping and reloading works. The site is hosted on cloudfront.net and I noticed with Wireshark it is using QUIC (http3). Turning off network.http.http3.enable in Firefox completely fixes it. Is anyone seeing anything like this?
