I am trying to use netflix on my macbook pro- what browser works best for that?
Any of them, however Silverlight is a Microsoft cross-browser plug-in that's used to play and protect the Netflix content and it needs to be updated often.
Sometimes one has to uninstall and reinstall it
Uninstall Silverlight: https://www.microsoft.com/getsilverlight/get-started/install/removing-silverligh t-mac.aspx
Reinstall Silverlight: https://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx

I accidentally deleted safari somehow and don't know how to get it back - right now I have firefox
Did you just delete it off the Dock?
Or is it totally gone from your machine? Because this isn't easy to do by accident in 10.7 or later.
If your having further problems (it seems you do) and/or Safari is really disappeared from your machine, then run through these Steps to fix your machine and return Safari.
