In about two weeks Mozilla will release an update for Firefox. Version 188.8.131.52 is addressing some possible security issues and any known regressions. Now, hopefully this update will go smoother than the 184.108.40.206 update did when Mozilla pulled a ‘Microsoft’. In this instance a ‘Microsoft’ is causing a problem with fixing another problem, which they quickly fixed with the 220.127.116.11 release. At this time there are no planned updates for Thunderbird which will remain at the current 18.104.22.168 version.
