When you open an encrypted webpage with Safari browser, Safari will check whether the certificate of the website is legal. If there is a lock icon next to the website URL, it means that the website has used the certificate and encrypted the information. The gray icon indicates that the standard certificate is used, and the green icon indicates that the EV certificate is used.
Click the sample lock icon to view the contents of the certificate. If the certificate of this website is signed by an untrusted issuer, you need to decide whether to trust this website, because this website is likely to be deceptive.
Safari browser will warn you of malicious websites that have been reported. When receiving the warning, please don't visit the website.

Differences between new Safari browsers:
1. Automatically jump after the password is automatically filled.
In the latest official version of iOS 12.2 system, after using iCloud keychain to fill in the password, Safari browser will automatically click the login button for you without manual jump.
2. The search bar has been improved.
After upgrading iOS 12.2, when you enter a keyword in the search bar of Safari browser, a blue arrow will be added next to other suggested keywords, and you can fill it in the search bar after clicking it.
Different from other browsers, this suggestion function does not directly launch a search after selecting a keyword, but puts the keyword into the search box, and then the user can edit it again. This function is actually similar to the "associative input" of the input method.
3. Security upgrade.
The security of Safari has been further improved after the update, mainly including:
When loading an unencrypted webpage, Safari browser will pop up a warning;
When iOS 12 was released, Apple emphasized the function of "preventing web tracking". However, this option is turned off by default and needs to be turned on manually. Now, the intelligent anti-tracking function will remain on by default, thus protecting the privacy of more users;
Give up supporting the expired "No Tracking" standard to prevent it from revealing personal information.
