ccleaner messes up formats

After running ccleaner the format of pages is completely messed up.

Firefox pages look different. The correction requires FF (tools/clear recent history) to restore the format, but I don't want to do this every time I run ccleaner.

Is there some adjustment that needs to be done on what ccleaner removes?

Site Preferences might be the option you're looking for, but just as a formality:

which versions of:

Firefox

Windows

CCleaner

are you running, and what exactly is getting messed up?

Firefox 16.0.1

Windows Vista (64 bit)

Ccleaner v3.26.1888(64 bit)

Which options (boxes checked) for Windows and Applications should be changed?

The default boxes are obviously not working.

The entire format is being changed by ccleaner.

Different format ????

Change of :-

Colour ?

Font ?

Size ?

I suggest two screenshots showing before and after.

Some suggestions:

Did this occur with a previous version of CC as well ?

Untick every box. Then tick one by one a group of boxes and run CC. This is how you can narrow down which group cleans those settings. When you know which group is responsible then you can narrow it down even more by ticking one box at a time and run CC again.

Ccleaner totally disarranges my formats when used. Suggested cures don't work other than the required tools/delete recent history for FF every time ccleaner is used. Decided to uninstall ccleaner. Thanks for the responses.
