Zen Browser 1.21.2b drops a necessary security update that patches multiple high severity memory corruption and sandbox escape flaws inherited from the Firefox 152 engine. The release finally resolves persistent tab routing bugs that previously overwrote active windows and forced background tabs to steal focus during multitasking.
