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.

• 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

• Right click the desired challenge and select Delete

• 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.
  • 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.
  • 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.
