If you use the Chrome browser, you should take a minute to be sure that it is updated to the latest version.
Step One: Click on the three dots in the top right of the browser right under the (X).
Step Two: Click on “Settings” – should be 3rd up from bottom.
Step Three: Click on the the three horizontal bars (“Main Menu”) next to “Settings” in top left of window that opens.
Step Four: Click on “About Chrome” at the bottom. Chrome should automatically start checking for and downloading updates.
Step Five: Click “Relaunch” when prompted.
This should probably be done weekly just to be on the safe side.
