Starting from version 20, Google Chrome does not allow direct installation of third-party plug-ins (which can be installed indirectly). The reason is that there are many insecure factors in third-party plug-ins, such as the possibility of collecting user privacy. This is worthy of recognition. However, Google Chrome is prepared to completely block third-party plug-ins in the name of security. More is that it is a good thing to generate third-party plug-ins in the name of security. It is undeniable that some plug-ins are really useful and popular with users. For example, some video plug-ins and online shopping plug-ins all have one thing in common, blocking annoying advertisements. For this reason, some plug-ins will also tamper with the webpage structure on the user side, so that users are not bothered; some third-party plug-ins imitate The paid version of the plugin is then available to users free of charge. That's why Google has been cracking down on third-party plugins before, and third-party plugins are still alive! The previous restrictions, the right to install third-party plug-ins to the user to decide, if you decide to install the security issues to be responsible for themselves, everyone can understand this, and changed to a comprehensive third-party plug-in, out There is another important reason to protect your own charging plugin. If you want to develop a formal plug-in, you need to register an account, $25 a, plug-in free or charge does have a revenue for the Chrome Web Store, if the plug-in is paid and gains, Google can also extract the commission & mdash; — third-party plug-ins for Google, a dime contribution is not! It can be said that Google blocked third-party Chrome plug-ins, it is for the purpose of making money and fighting against some plug-ins that Google does not like. Previously, click on the top right corner of the Chrome “Customize & Controls menu, select “Tools”, then select “Extensions”, then drag the third party plugin into the extension window to install the third party plugin indirectly. Users strengthen security detection. See here, presumably everyone does not believe that Google is really thinking about the security of users browsing! If it is really to improve the security of the Chrome browser, what should I do to curb malicious plugins? First of all, although there are some malicious plug-ins in the third-party plug-ins, they should not be completely blocked due to squandering. Instead, they should establish a security detection mechanism, such as blacklist mechanism, automatic identification mechanism of malicious code, etc., to filter unsafe third-party plug-ins. Secondly, you can slowly guide users to use the plug-ins in the Chrome Web Store to cultivate good usage habits. Finally, a complete security protection system should be established. If the user installs an unknown third-party plug-in, the Chrome browser will automatically disable the privacy of the plug-in mobile phone user, but it does not affect the normal use of the plug-in!
