Chrome Developer Tools Not Working

Recently I had to replace my Windows PC at work, and as a result, had to reinstall all of my applications, including Google Chrome. When I tried to open Chrome Developer Tools using the F12 key, nothing happened. The Inspect option seen when right-clicking on a web page was grayed out. I opened the drop-down menu to try to open DevTools from there, and that option was also grayed out.

Developer Tools is disabled

Several searches indicated that one could look at Chrome Policies (accessible at chrome://policy if you’re running Chrome) to see if it was disabled there. Sure enough, that was the case.

Chrome Policies are not editable from this page; in Windows one must edit them via the Windows Registry.

Open the Registry using regedit.exe from a Command Prompt or a shortcut in the Start Menu, and navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome] and set the key called DeveloperToolsDisabled to 0.

Close the Registry Editor, go back to the Chrome Policies tab, and click the Reload button in the upper left-hand portion of the screen.

The “true” value for the DeveloperToolsDisabled Policy Name should change to “false”.

Now you should be able to open DevTools again!

Code School will be Having a Black Friday Special!

I have found Code School to be a great resource both for those just learning to code as well as those who are experienced coders, but want to learn a new programming language. It has multiple paths: Ruby (including Ruby on Rails), JavaScript (includes jQuery and CoffeeScript), HTML/CSS, iOS, Git, and an Electives path for miscellaneous technologies such as R and Chrome DevTools.

The normal price for a subscription at Code School is $29 per month, or $290 per year. However, it appears that they intend to run a Black Friday special for yearly subscriptions. The price will be revealed this Friday. If you don’t already have a subscription, or your subscription is about to run out, this could be a good time to sign up!

Unfortunately, Code School is still lacking Python, though you can learn it at Codecademy (which is free).
