One of the easiest and most important things you can do to help keep your computer secure is to make sure you have a current version of your web browser. Firefox is a great web browser and is very easy to upgrade.
1. Head to the top left menu (File, Edit, View…) and select Help. In the drop-down menu that appears, select “Check for Updates…” . Sometimes a few small updates will be completed, and sometimes a new full version will be installed. Also note that Firefox may need to restart itself, which is totally normal.
This simple technique will help keep your computer safer.
