Answer 1

Hello lea,
this is what those mean:
Warn me when sites try to install add-ons :
With [[Customizing Firefox with add-ons|Add-ons]] you can enhance Firefox's experience. However, some add-ons can be malicious so that's why Firefox warns you before installing them by default.
Block reported attack sites :
Attack sites are those sites that can install malware on your computer. Normally, Firefox blocks that. The same goes for
Block reported web forgeries , where Phishing sites are being blocked. See [[How the phishing and malware protection in Firefox works]].
Also, those information can be found in the [[Options window - Security panel]] KB article.
