Set default zoom in Safari
You can set a default zoom level for Safari. In this way you don't have to hit Cmd+ (or Cmd-) every time you start Safari
1) Open Textedit app, go to menu Format and select Make Plain Text
2) Copy and paste in the following:
body {
zoom: 130%;
}
You may change 130 to whatever number suits you
3) Save the file with .css extension (for example Safarizoom.css) in Library > Safari folder
4) In Safari, go to Preferences > Advanced. Under style sheet, select Other... and point to the file you created
