Highlight Elements Plugin for Selenium IDE ver 1.0 Released

The Highlight elements button is added the toolbar of the Selenium IDE.

The Highlight Elements plugin for Selenium IDE is now available on the Firefox addons site.

This plugin for Selenium-IDE highlights elements specified in the Selenese commands on the web page as the test case is executed. Once this plugin is installed, a highlight elements button will be available on the Selenium-IDE main window and Sidebar. See the screen shot for details.

This plugin is very useful in debugging selenium test cases, maintaining selenium test cases and giving demos to stakeholders too. See the post Exploratory Maintenance and Debugging of Selenium Tests.

Mini user guide for the plugin

The element specified in the command is highlighted as the command is being executed.

  • Click the Highlight elements button on the Selenium IDE to turn on element highlighting.
  • For best effect, reduce the execution speed using the slider.
  • Click the Highlight elements button on the Selenium IDE again to turn off the element highlighting.

To use this plugin, you will need to install Selenium IDE addon of at least version 1.0.4 first.


  • Saving / loading status of the button
  • Refactoring for reducing technical debt
  • Internationalisation

Known Issues

  • Some types of elements cannot be highlighted.

Other Thoughts

I had wanted this simple but very useful feature in Selenium IDE for a long time. I had a lot of fun developing this plugin. Some of the interesting things this time include creating a separate reusable module to provide plugin registration and cleanup, and a new (for me), cleaner, more readable and reusable approach to overriding methods.

Get it from the Firefox addons website here. Don’t forget to let me know what you think. As usual any comments, improvements, suggestions, advise, criticism,… are always welcome.

    Excellent. I have been waiting long time for this.

  3. Sikander says:

    Really good feature. Instead of adding as a plug-in, why cant it integrated with Selenium IDE tool in the coming release?

    • Samit Badle says:

      Hi Sikander,

      I am glad you like the plugin. There are two main reasons why it is a plugin.
      First, It is just easier to release a plugin than to get someone to apply a patch in Selenium IDE.
      Second, You have a choice if it is a plugin. If you don’t like it or is does not work for you, you can get rid of it.

    Thanks for such great tool.
    Just one question…
    While executing recorded part, we are getting error as “Element IM_MENU not found “.
    what could be the problem.

    • Samit Badle says:

      Hi Bipin,

      Try to uninstall the Selenium IDE plugins to determine if the error is caused due to one of the plugins. If you can isolate if one of my plugins is causing the error, I can try to look into it.


  6. Bipin says:

    I have checked I have only Firebug plug-in installed. I have removed fire-bug plugin. Same error continues…..
    I have checked the source of web page is ->


    So.. there is Frame having name as “IM_MENU”….
    Could you please tell me what went wrong ?

    • Samit Badle says:

      Hi Bipin,

      For general queries about Selenium, it might be best to drop your query on http://stackoverflow.com/ or the Selenium users mailing list. This would allow more people to benefit from the answers. In case you find a problem or have any suggestions about my plugins, feel free to drop me a comment.

    My task at work right now is to take a bunch of IDE recordings and make them RControllable.

    When these scripts were recorded, the tester accepted whichever locators the IDE chose, while documenting or commenting none of them, so there are hundreds of mysterious xPath and name locators lying about.

    Thank heavens for the Highlight Elements plug-in.

  8. Frisco Del Rosario says:

    One thing: Whether clicking the toolbar icon on or off, it’s difficult for me to see which. How might on and off be more clearly differentiated?

    • Samit Badle says:

      Hi Frisco,

      I thought atleast on Windows, it was very obvious. What OS are you using? I will be happy to take a second look at it.


  9. Hi Samit – Lot of thanks that you have developed such plugin for selenium IDE. You might have noticed that this plugin do only works with selenium ide 1.0.7. Unfortunately it does not work with later version. I installed 1.0.8, 1.0.9 and 1.0.10 and it only works with 1.0.7. Don’t you have plan to make it work with later versions? Please do it.

    • Samit Badle says:


      I use the plugin myself without any problems on Selenium IDE v1.0.11-snapshot. Can you try uninstalling all firefox addons and just installing Selenium IDE 1.0.10 and then the plugin? It should solve any state related issues. Let me know if it helps.


      • Samit Badle says:


        The highlight element plugin puts a toolbar icon on the Selenium IDE toolbar. Please let me know if you see that. You can turn on the element highlighting on or off using this icon. By default, it is turned off. Let me know if this helps.

    Hi – Yes I saw the yellow button on toolbar with every selenium IDE versions and that is clickable too. Problem was it could not highlight the elements when the test case runs. Anyway, I’ll try doing what you said in reply ‘February 14, 2011 at 6:39 pm’ and will let you know if it still works or not.
