HUGE BUGS with Speed Dial

Huge bug in speeddial. I have FF 56.0. Everytime I start FF and go to my
dials I get 2 big bugs. The first bug is every time I start FF I get a
pop saying, "Welcome to the FVD Speed Dial." Why is that shit
happening??? Look at the attached image.

The 2nd bug is that theres a speed dial icon on my address bar. Look at the image atrtached.

How do I fix this?? Is there an update??
