What should I do if CCleaner Browser crashes or won't open?

If CCleaner Browser crashes or won't open, try the following troubleshooting options:

  1. Close the Browser and open it again
  2. Close the Browser and restart your PC
  3. If you're able to open the software but it crashes afterwards, open the CCleaner Browser menu and click More Tools, then Extensions. In this screen, disabled all enabled extensions by clicking the slider for each extension. (The slider will be blue and pushed to the right if enabled, grey and pushed to the left if disabled.)
  4. Uninstall the Browser (you can also do this using the CCleaner desktop application) and reinstall it
