Hi.
Long time user of CCleaner and I downloaded the latest update last night. V3.11.1550 64 Bit. Immediately after running the cleaner (with the same settings I always use - no previous problem like this) I opened Firefox V6.0.2 to check a website and the page format was all broken. Checked a good few more sites that I usually browse and they were broken too yet worked perfectly fine in IE9. Bizarrely or a bit of good luck this site is working fine in Firefox.
The settings I use in the Firefox/Mozilla section in CCleaner are, Internet cache and internet history download history and session are all checked.
I've rebooted a couple of times since running CCleaner and keep going back to these websites like the BBC but they're still broken with pictures all over the place and the websites links in a big scrollable list yet they work fine in IE9.
Windows 7 home premium.
TIA
