I ran a search and couldn't find any related article.
I tried R-Wipe & Clean yesterday (July 31, 2012). I downloaded the latest version from the official page.
The version of Firefox I use is 14.0.1.
After cleaning the browser, I was unable to display web pages properly. No styles were loading properly.
It seems the application is cleaning 'too deep'.
At the moment, I have uninstalled the application and I am unable to reproduce the problem. But, I wanted to report it. I noticed this problem when trying to access the overview page for the application Paragon disk wipe 11 personal. The page appeared as plain text.
The problem occured when I tried to use competitive applications. Other vendors do have the same problem.
The only solution I have found is to uninstall Firefox and reinstall it completely. This solves the situation.
Testing, doing screenshots, etc takes me time. I cannot guarantee I will be able to do it.
