22x critical severity CVEs
7x high severity CVEs
10x moderate severity CVEs
1x low severity CVE

Details of how to install updates for Firefox are here. If Firefox is your web browser of choice, please update it as soon as possible to resolve these security issues.

Generally, Mozilla Firefox updates install without issues, however as always I would recommend backing up the data on any device for which you are installing updates in order to prevent data loss in the rare event that any update causes unexpected issues.

Thank you.
