1. Close Firefox completely. (File->Exit on Windows/Linux, Firefox->Quit on Mac)

2. Rename the Firefox installation folder or move it elsewhere.

  • Windows: This is usually C:\Program Files\Mozilla Firefox. "Mozilla Firefox" can be renamed to "Old Firefox"
  • Mac: This is usually Macintosh HD/Applications/Firefox.app. Macintosh HD/Applications can be opened in Finder, and Firefox can be dragged to Trash.
  • Linux: The install location varies based on distribution and installation method. Linux distributions usually don't put Firefox in its own folder, so this method can't be used.

3. Download Firefox again from www.mozilla.com and install. (Installation instructions for Windows, Mac, Linux ) 

4. If this fixes the problem, you can optionally check the old install folder for global extensions, components, or corrupt/locked files.
