Google released the latest Chrome 88 browser on January 19, which removed support for FTP and Flash Player, added a paging search, began accepting Manifest V3-based extensions, and patched 36 security vulnerabilities.
It should be natural for Chrome 88 to remove support for Flash, because Adobe has terminated support for Flash Player on December 31 last year, which means that Adobe will no longer release any bug fixes for Flash Player. In addition, Adobe has also Flash content was blocked on January 12.
Google has long wanted to remove the FTP function of Chrome, which is a file transfer protocol between the client and the server. Google released Chrome 81 in April last year and closed the support for FTP by default. Chrome 82 completely removed the code and resources related to FTP in the browser, but the world was busy dealing with the COVID-19 epidemic at the time. Google did not want to cause too much burden on users, and temporarily decided to let FTP return to Chrome.
However, Chrome 88 has removed support for FTP URLs. , The FTP implementation in Chrome does not support encrypted transmission, and there is no proxy, and the proportion of using FTP in the browser is very low, it is not worth investing in manpower to improve, and there are more powerful functions on all operating systems FTP client can be used.
The page search finally appeared on Chrome 88, but it is still an experimental feature that must be manually enabled. After enabling it, you can see a drop-down function on the right side of the page tab. After clicking it, you can see the page with the title and URL. List, you can also directly enter the search string.
On the other hand, Chrome 88 also began to support Chrome extensions based on Manifest V3. Manifest files are used to allow developers to declare specific resources used by their programs, such as various files or APIs. Google revises the Manifest specifications of Chrome extensions based on the features of the Chrome browser, whether in terms of security, performance or privacy. There is a significant improvement.
For example, it prohibits the use of remote hosting code to avoid abuse by hackers; it also replaces background pages with service workers, because the former only appears in memory when needed, so it can be used Less system resources, unlike the long-resident background page, which will continue to consume system resources; it will also give users more control over extensions, such as managing how extensions use and share data. Future versions will adopt new ones The installation process allows users to retain sensitive permissions during installation.
Every new version of Chrome will patch vulnerabilities, and Chrome 88 is no exception, but only one vulnerability is classified as Critical. It is CVE-2021-21117. The vulnerability is described as “Insufficient implementation of policies in Cryptohome”. Discovered by information security researcher Rory McNamara, he was also awarded a $30,000 bonus for catching leaks.
