Due to several newly discovered and closed bugs in recent times, it’s advisable to update your browsers, both Firefox and everything based upon Google’s Chrome and Chromium engines.
See here and here for Firefox, here and this and that for Chrome.
The fastest of my systems to update these (or their hardened derivates) were DivestOS with updates for their Mull and Mulch browsers, and Arch Linux with the new Firefox and Chromium browsers – thanks for all of your work, it’s really appreciated!
Thanks to you for reading, and for considering to staying safe.
