If you are using Firefox, whether on Windows, Linux or Mac, it's in your best interest to go and get the latest version from Mozilla's site! Firefox 220.127.116.11 fixed various issues with the browser, including some related to memory leaks and privilege escalation (which can ultimately result in system compromise). As far as I can tell, all the bugs with updates removing bookmarks and breaking plugins have been fixed, and after updating everything seems to be fine, even 3rd-party plugins.
