by Kenji Nakamura 76 views

Hey guys! Are you tired of Chrome constantly asking you for permission every time you click on a custom URL protocol like telnet://? It's a common issue, especially after you've set up an external handler for these protocols. You've gone through the process of configuring Chrome to use an external application to handle these links, but the persistent prompts are driving you nuts, right? Don't worry, you're not alone, and we're here to help!

This comprehensive guide will walk you through the steps to stop Chrome from prompting you every single time you try to open a URL with a custom protocol. We'll explore the reasons behind this behavior and provide a step-by-step solution to make Chrome remember your preference, ensuring a smoother browsing experience. Get ready to say goodbye to those annoying prompts and hello to seamless protocol handling!

Understanding the Issue: Why Does Chrome Keep Prompting?

Before diving into the solution, let's understand why Chrome behaves this way. Chrome's security model is designed to protect you from malicious websites that might try to exploit custom URL protocols. When you click on a link like telnet://some-address, Chrome, by default, wants to ensure that you actually intend to open an external application. This is a good thing in terms of security, but it can be frustrating when you've already configured a handler and trust the protocol.

The prompt you're seeing, such as "Open xdg-open?" followed by the URL, is Chrome's way of verifying your intent. It's a security measure to prevent potentially harmful applications from being launched without your explicit consent. However, once you've set up a handler and you're confident in your configuration, these prompts become repetitive and unnecessary.

The core reason for this behavior is that Chrome doesn't automatically remember your preference for handling specific protocols. It treats each click as a new instance and requires confirmation every time. This is where our solution comes in. We need to tell Chrome to remember our choice and stop prompting us for the same protocol handler repeatedly. We'll achieve this by modifying Chrome's settings and potentially making adjustments to the system's protocol handling configuration.

It's important to note that this issue is particularly prevalent on Linux systems where xdg-open is commonly used to handle external URL protocols. xdg-open is a command-line tool that helps open files and URLs using the preferred application for the given type. When Chrome uses xdg-open, it triggers the prompt because Chrome wants to ensure that you trust the application that xdg-open will ultimately launch. This extra layer of security, while beneficial, can lead to the annoying prompts we're addressing today.

So, to recap, the prompts are a security feature, but they can be disabled once you've established trust in your configured protocol handlers. Now, let's jump into the solutions and get those prompts out of your way!

Step-by-Step Solution: Stop Chrome's Prompts for External URL Handlers

Okay, let's get down to business and eliminate those pesky prompts! We'll break this down into a step-by-step process to make it super easy for you to follow along. We're going to be focusing on configuring Chrome to remember your preference for handling external protocols, specifically on Linux systems where this issue is most common. Follow these steps, and you'll be browsing seamlessly in no time!

Step 1: Identify the Protocol and Handler

First things first, let's make sure we're clear on the protocol causing the issue. In the original scenario, it's the telnet:// protocol, but this solution can be applied to other protocols as well. Also, identify the handler you've configured. In many cases, especially on Linux, this is likely xdg-open. Knowing these details is crucial for the next steps.

  • Protocol: The URL scheme that triggers the prompt (e.g., telnet://, ssh://, mailto://).
  • Handler: The application or command that handles the protocol (e.g., xdg-open, a specific application like PuTTY).

Step 2: Modify Chrome's Protocol Handling Settings

Chrome has a setting that allows you to manage how it handles external protocols. We're going to use this to tell Chrome to trust our handler for the specified protocol.

  1. Open Chrome's Settings: Click on the three vertical dots in the top-right corner of Chrome, and then select "Settings".
  2. Navigate to Privacy and Security: In the Settings menu, find and click on "Privacy and security".
  3. Go to Site Settings: Under "Privacy and security", click on "Site Settings".
  4. Find Protocol Handlers: Scroll down in Site Settings until you find "Handlers" or "Protocol handlers" and click on it. If you can't find it directly, try searching for "Handlers" in the settings search bar.
  5. Manage Handlers: Here, you should see a section that lists registered protocol handlers. This is where you can manage which sites are allowed to open external applications for specific protocols.

Step 3: Add an Exception for the Protocol

Now, we're going to add an exception to Chrome's settings so that it knows to trust our handler for the telnet:// protocol (or whichever protocol you're dealing with).

  1. Check the "Don't allow sites to handle protocols" List: In the Protocol handlers settings, look for a section that lists sites that are not allowed to handle protocols. If you see the protocol you're working with (e.g., telnet), remove it from this list.
  2. Add an Allowed Handler (If Necessary): Chrome might not have a specific interface to add allowed handlers directly. Instead, you might need to trigger the protocol from a website to see the prompt again. This time, when you see the prompt, check the box that says something like "Remember my choice for all telnet:// links" (the exact wording may vary). Then, click "Open xdg-open" or the appropriate handler.

Step 4: Verify the Configuration

After making these changes, it's essential to verify that they've taken effect. Here's how:

  1. Restart Chrome: Close and reopen Chrome to ensure the settings are fully applied.
  2. Test the Protocol: Click on a telnet:// link (or the protocol you're working with) on a webpage or in an application. You should now be able to see if Chrome prompts you every time or not.
  3. Check Handlers Again: Go back to Chrome's Protocol handlers settings (as described in Step 2) and see if the handler is listed as allowed. This will give you visual confirmation that Chrome has remembered your choice.

Step 5: Troubleshoot (If Prompts Persist)

If you're still seeing prompts after following these steps, don't panic! Here are some troubleshooting tips:

  • Clear Chrome's Cache: Sometimes, cached data can interfere with settings. Clear Chrome's cache and try again.
  • Check System-Level Protocol Handlers: On Linux, xdg-open relies on system-level configurations. Make sure your system is correctly configured to handle the protocol. You can check this by using the xdg-settings command in the terminal.
  • Create a Chrome Profile: If nothing works try creating a new Chrome Profile. Sometimes Chrome settings get corrupted and a fresh profile could be the solution.
  • Chrome Extensions: Some extensions might be interfering with protocol handling. Try disabling extensions one by one to see if any of them are the culprit.

By following these steps, you should be able to stop Chrome from prompting you every time you click on an external URL protocol. It might take a little bit of tweaking, but the result is a much smoother and more efficient browsing experience. Now, let's move on to some additional tips and tricks to further enhance your protocol handling!

Advanced Tips and Tricks for Protocol Handling

Alright, you've successfully stopped Chrome from prompting you repeatedly – awesome! But let's take things a step further. Here are some advanced tips and tricks to fine-tune your protocol handling and ensure a seamless experience across your system.

1. Configuring System-Wide Protocol Handlers (Linux)

On Linux, the xdg-open command plays a crucial role in handling external protocols. It acts as a dispatcher, determining which application should handle a specific protocol based on system-wide settings. If you're still facing issues, it's worth checking your system's protocol handling configuration.

  • Using xdg-settings: The xdg-settings command is your best friend here. It allows you to query and modify the default applications for various URL schemes. Open your terminal and try the following commands:

    xdg-settings get default-url-scheme-handler telnet

    This command will tell you which application is currently set to handle telnet:// URLs. If it's not what you expect, you can change it using:

    xdg-settings set default-url-scheme-handler telnet your-telnet-application.desktop

    Replace your-telnet-application.desktop with the actual .desktop file for your preferred telnet client. This file contains information about the application, such as its name, icon, and execution command.

  • Finding .desktop Files: .desktop files are typically located in /usr/share/applications/ or ~/.local/share/applications/. You can browse these directories to find the correct .desktop file for your application.

2. Creating Custom Protocol Handlers

Sometimes, you might want to create your own custom protocol handlers. For example, you might want a specific script to run when you click on a custom URL scheme. This is entirely possible, and it's a great way to extend your system's functionality.

  • Creating a .desktop File: Start by creating a .desktop file for your custom handler. This file will define the command to execute when the protocol is invoked.

    [Desktop Entry]
Type=Application
Name=My Custom Handler
Exec=/path/to/your/script %u
MimeType=x-scheme-handler/myprotocol;

    Replace /path/to/your/script with the actual path to your script, and myprotocol with your custom protocol scheme (e.g., myprotocol://). The %u is a placeholder for the URL.

  • Registering the Handler: Place the .desktop file in ~/.local/share/applications/ and then register it with xdg-settings:

    xdg-settings set default-url-scheme-handler myprotocol my-custom-handler.desktop

3. Using Chrome Extensions for Protocol Handling

Chrome extensions can also help with protocol handling. There are extensions available that allow you to customize how Chrome handles specific protocols or even create custom protocol handlers directly within the browser.

  • Search the Chrome Web Store: Look for extensions related to "protocol handling" or "URL handling". Read the reviews and descriptions carefully to find an extension that suits your needs.

4. Handling Multiple Protocols

If you're dealing with multiple protocols, it's essential to keep your configuration organized. Use descriptive names for your .desktop files and document your settings. This will make it easier to manage and troubleshoot your protocol handlers in the future.

5. Security Considerations

While custom protocol handlers can be incredibly useful, it's crucial to be mindful of security. Only configure handlers for protocols you trust, and ensure that the scripts or applications you're using are from reputable sources. Malicious actors could potentially exploit custom protocol handlers to execute arbitrary code on your system.

By implementing these advanced tips and tricks, you can create a powerful and efficient system for handling external URL protocols. Whether you're a developer, a system administrator, or simply a power user, these techniques will help you streamline your workflow and enhance your browsing experience.
