CookieSlice is a Chrome Extension which adds a feature to the browser. It allows you to specify cookies by name to keep unique per Browser Tab instance. This feature allows you to keep unique sessions for servers that use cookies to store the session ID. This feature allows you to have a unique session per tab. By using this feature, you can be more secure as it prevents a hacker from stealing your session id from one browser tab and trying to hack your account. In addition, it prevents the attacker from tracking you on the server.

It also gives you the flexibility to choose which cookies to intercept or choose to intercept all incoming cookies. By intercepting this cookie, you can have a unique session per tab.
