Webpages not viewing properly after run ccleaner

I have firefox 7.1 and since I have used the ccleaner certain webpages are not displaying properly like they have a missing style sheet. This happens especially with ebay which I use a lot. Can anyone help?

Try this, no guarantee it will help though:

  1. Start Firefox.
  2. Use Firefox's own built-in cleaners in: Tools->Clear Recent History

    Warning: Make sure you untick/disable the box “Site Preferences” otherwise it will delete all your bookmarks!!!

  3. Close Firefox, and wait maybe 10 to 20 seconds to make certain it's completely closed. Also if you use Thunderbird make certain all processes of it are exited as well!
  4. Run CCleaner.
