Security Settings for Different Browser
INTERNET EXPLORER
In order to change the security in Internet Explorer, select Tools | Internet Options, and then select the Security tab. Here, you will find a list of security zones for which you can set a specific level of protection. The Internet zone is where all sites that a user navigates to are initiated. The High security settings disables features including ActiveX and JavaScript to make the browser more secure. The Custom Level button allows you to refine the selection of features that are disabled in the High security setting.
The trusted Sites zone contains a list of sites that you consider to be safe to visit. Click on the Sites button to open a window where you can add or remove trusted sites. If your Internet zone security level is set to high, some sites that you wish to visit might not function properly, adding them to the trusted sites list will ensure that features like ActiveX and scripting are enabled for these sites.
To manage your cookies and extensions , move to the Privacy tab. Set the privacy settings to High and then click on the Advanced button. In the Advanced Privacy Settings window, check the Override automatic cookie handling checkbox. Also, select Prompt for First-party and Third-party cookies. This way, you will get a notification every time a site tries to send cookies to your system. You can also check the Always allow session cookies option as session cookies are deleted each time the browser is closed and are therefore less dangerous.
To reduce the number of cookies notifications from frequently visited sites, you can select the Sites button and add sites for which you wish to always allow or block cookies.

In the Cookies sections, check the box for Accept cookies from sites and select Ask me every time in the dropdown menu. This gives you control of the cookies that are sent to your system.
Under the security tab, check the box for Warn me when sites try to install add-ons so that you can keep track of the sites and the type of add-ons being installed. Also, if you wish for Firefox to remember your passwords, then it is advisable to enable the Use a master password function, which encrypts all your login details.
In the Content tab, you will find an option to control Java. Uncheck the Enable Java option to prevent sites from running applications on your computer. You can also select the Advanced button to disable certain features of JavaScript.
