Firefox's User Agent will remove the example analysis of CPU architecture information. I believe many inexperienced people are at a loss about this. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Mozilla plans to remove CPU schema information from Firefox's User Agent (user agent) and several supported API to reduce the "digital fingerprint" of Firefox users. The Web browser automatically displays information to the Web site that the user opens in the application, while the user agent displays data about the browser and browser version, operating system, and CPU schema.

Fingerprint recognition scripts use user agent information and other information, such as language and location, to create digital fingerprints, and the accuracy of fingerprints increases with the number of unique data points.

However, Firefox, known for its emphasis on user privacy, said that CPU architecture information from User Agent will no longer be displayed in Firefox Nightly 69.

CPU schemas will be distinguished in the following ways:

32-bit Firefox on 32-bit operating systems.

32-bit Firefox on 64-bit operating systems.

64-bit Firefox on 64-bit operating systems.

Firefox users using Firefox 69 will notice that scripts that return user agents will no longer distinguish information, as shown in the screenshot below when searching for "check user agent" on Google:

Mozilla / 5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko / 20100101 Firefox / 69.0

This change affects 32-bit Firefox installations running on 64-bit versions of Windows or Linux operating systems. Starting with Firefox 69, these versions will use the following user agents:

Linux:Linux x86_64 instead Linux i686 on x86_64

Windows: Win64 instead of WOW64

After reading the above, have you mastered the method that Firefox's User Agent will remove the sample analysis of CPU architecture information? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
