To help ensure the security of our digital lives, Mozilla is adding an extra layer of security to the Linux, Android, and macOS platforms by implementing an enhanced stack smashing protection in Firefox 65, which will be enabled by default for all users. Additionally, Firefox 65 comes with an updated Content Blocking section in the Privacy & Security panel and much simpler blocking options in Control Center's Options page. Among other noteworthy improvements coming to the Firefox 65 web browser, we can mention the ability to set Firefox to warn you when closing the window even if it's configured to automatically restore the last browsing session on the next launch, as well as support for reporting the memory usage for each resource in the updated Task Manager page that's accessible if you type about:performance in the address bar.
