- Click Load unpacked and select your extension’s directory.
- Open your extension, right-click, and choose Inspect.
The Chrome Developer Tools window appears.
This window shows:
| Tab | Use |
|---|---|
| Elements | Inspect HTML/CSS. |
| Console | View logs, errors. |
| Sources | Debug JavaScript. |
| Network | Analyze requests. |
| Application | Check storage, resources. |
Explore the tabs to see code, make changes, and debug in real time!
Mastering Breakpoints And Code Inspection
Debugging is like being a detective for code. The Debugger for Chrome Extension turns any developer into a master sleuth. Mastering breakpoints and code inspection can transform a daunting task into a smooth sail. Let’s dig into this crucial debugging feature!
Setting And Managing Breakpoints
Breakpoints are a debugger’s best friends. They let you pause code at critical spots. With the Chrome Extension, setting them up is a breeze. Check out this process:
- Open your JavaScript file in the Developer Tools (press F12).
- Click on the line number where you want to stop.
- A blue marker appears, indicating an active breakpoint.
But there’s more! You can manage breakpoints too. Here’s how to stay organized:
- Disable a breakpoint by clicking on the blue marker.
- Remove it entirely by right-clicking and selecting ‘Remove breakpoint’.
- To see all breakpoints, check the ‘Sources’ tab panel.
Inspecting Variables And Call Stack
Peeking inside your code is essential for fixing bugs. Use the Debugger to inspect variables on the fly:
- Hit a breakpoint and look to the ‘Scope’ section.
- Here, variable values are on full display.
- Hover over variables in your code for a quick view.
The call stack is another hero in the debugging story. It shows the path your program has taken. Follow these steps to navigate it:
- With an active breakpoint, go to the ‘Call Stack’ pane.
- See a list of functions that have been called recently.
- Select a function to jump to its location in the code.
Remember, mastering these tools sharpens your debugging skills. The Chrome Extension makes it easy and fast. Happy coding and happy debugging!

Troubleshooting Common Issues
Troubleshooting common issues in ‘Debugger for Chrome’ often feels daunting to even seasoned developers. But fear not! We’re set to demystify some frequent hiccups encountered while working with content scripts and background pages, as well as managing asynchronous code and events. These tailored tips guarantee smoother debugging sessions ahead. Let’s dive right in.
Debugging Content Scripts And Background Pages
Encountering problems with content scripts and background pages? You’re not alone. Let’s address these usual suspects head-on:
- Check manifest file – Confirm if ‘debuggable’ is true.
- Ensure proper loading – Scripts might not load correctly. Reload the extension.
- Look at the console – Chrome DevTools highlights issues here.
- Source mapping – Verify source maps if using transpilers like Babel.
Handling Asynchronous Code And Events
Asynchronous code, while powerful, often leads to tricky debugging scenarios. Embrace these strategies for better control:
- Use breakpoints wisely – Place them in callbacks and promises.
- Apply ‘async’ and ‘await’ – Simplify your asynchronous logic.
- Monitor event listeners – Keep an eye on these through the ‘Sources’ panel.
- Trace execution – Step through your code with the debugger step controls.
Remember these pointers should guide you through most scenarios that come your way.
