No "https" on websites

Hello. I recently noticed that I no longer have the secure "https" when I visit pages. Previously, it was automatically there on all I visited.  I am unsure as to why this changed… Is there a setting on my computer that I need to change to resume back to the https? My computer techie skills are woefully insufficient, so please excuse incorrect terms, etc. Thank you for any assistance rendered.

Also, I just tried to re-install the secure search add on…and it says it is already installed…  :(
