User Agent

Input custom User Agent

Introduction

It is recommended to leave the User Agent field blank to use the default configuration. Only modify it if necessary, as incorrect or outdated entries may prevent access to websites.

The User Agent field allows you to specify a custom User Agent string for your browser. This string tells websites about the browser, operating system, and device you're using.

Important Notes:

• Entering an incorrect User Agent will prevent you from accessing the website. If the format is wrong or the string doesn't match the expected format, the website might block your access or display errors.

• The User Agent must follow a specific format to be valid. Ensure that the string you enter adheres to the correct syntax.

• Older browser versions may not be supported. Using a very old User Agent string may result in being unable to access some websites that require newer versions of browsers for compatibility or security reasons.

The website error occurs when access is denied due to an incorrect or outdated user agent

User Agent Format

A valid User Agent string typically includes the following elements:

1. Browser Name and Version: E.g., "Mozilla/5.0"

2. Operating System: E.g., "Windows NT 10.0" or "Macintosh; Intel Mac OS X 10_15_7"

3. Device Type (optional): E.g., "iPhone; CPU iPhone OS 14_4 like Mac OS X"

4. Rendering Engine: E.g., "AppleWebKit/537.36"

Example of a valid User Agent string:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36

Troubleshooting

Resolving User Agent Issues:

• If you encounter issues accessing websites after entering a custom User Agent, double-check the string for correct formatting.

• If the string is outdated (e.g., a very old browser version), the website may refuse access. Ensure the browser version is up-to-date to avoid compatibility problems.

• Note: You can leave the box empty if not needed.
