Unavailable: Browser Restart Needed

Good morning

 

I have encountered this problem today.  I couldn't dind a way to "Restart" the browser that got rid of this problem, so I ended up rebooting the laptop.

 

Identity safe then worked... for a little while then I get the same error message.  This error appeared both times after manually refreshing a website by hitting the F5 button.

 

Any help would be appreciated
