Firefox: 93.0 OS: openSUSE Tumbleweed 20211030 KDE Plasma: 5.23.2 Qt: 5.15.2 Firefox now freezes almost immediately upon launching. I have performed all the troubleshooting steps described at https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding I have performed the Refresh procedure and disabled hardware acceleration. I have no themes or add-ons installed. The freeze is permanent; it doesn't recover. I have to perform a "kill -9" on the firefox process. When the freeze has occurred, the CPU is not spiked. The "top" command is showing GeckoMain at the top of the list.
