do you know which browser you are using ?
that is usually just a switch that you can turn on and off.
but i cant tell you how unless i know which browser it is.
usually chrome or the internet explorer or firefox
the e for the internet explorer is gone because windows 10 replaced it with the new edge
there are a few things you can do about the bookmarks
try logging in to google at
try holding ctrl and shift down and hitting B
and this one gets more complicated but you can try these steps
or you can try just reinstalling the chrome
