Removing specific values from your browser's local storage will solve many problems related to the browser crashing or freezing on FreeCodeCamp.

This solves, as example, a common problem with browser hanging out in a challenge's page after saving a response with an infinite loop.

When this happens, you must delete the value in localStorage storing that response.

In Chrome:

  • On freecodecamp.com, open your developer tools.
    • More tools > Developer tools (or Ctrl + Shift + I (Windows), Cmd + Opt + I (Mac))
  • Navigate to the Resources tab
  • Expand the Local Storage item in the left pane
  • Select http://www.freecodecamp.com
  • Find the challenge you wish to delete data in the right pane Finding a key in localStorage Chrome Developer Tools
  • Right click the desired challenge and select Delete

In Firefox:

  • On freecodecamp.com, open your web console with
    • Ctrl + Shift + K
  • From there, using directly the console:
    • Type console.log(localStorage); and hit Enter.
    • Click in Storage link. Print the localStorage Object from web console and show the Storage
    • The Storage panel will appear at right.
    • Filter the results to find the Algorithm, Front End Project or Challenge causing the problem.
    • When located, mouse over it and click the x at right. Click the x for deleting the value entry.
    • Once removed, check if the problem was solved. Refresh or close and open the browser if necessary.

Note: This can also be done with the Storage Inspector, but seems like Firefox hangs out when there are so many values.
