I would like to add a new 10-page chapter.
1-2 pages about DNSsec.
That is the new trend and all the organizations will move towards DNSsec because DNS has many vulnerabilities like DNS poisoning.
Also that for the time being DNSsec it is not commonly held because of its complexity and of the many configurations it needs.
Finally 1 picture of how it works and give an example.
3-4 pages about GDPR.
What is GDPR?
Which are considered personal data in web browsers?
Which are the personal data a browser can keep and afterwards what can the sites keep through the browsers?
How gdpr protects personal data for example browsers-companies can not sell them to 3rd parties. Why do they keep personal data and for how long?
which are the responsibilities of web browsers
and a reference about what is happening in the USA.
finally a subsection about extensions.
advantages and disadvantages of plugins( some plugins are open source and are vulnerable while others can mitigate a vulnerabillity)
to choose 4 plugins and analyze them for example adblocker, wordpress, password management (key pass) and vpn (proxies).
in the end to summarize saying that it seems it is relative the sign they end up with.(f.ex. adblocker has many positives while wordpress many negatives )
