My system slows down and eventually I get an unresponsive script with a name that starts with Chrome. When I do a search I find I have 7 chrome.manifest files, 8 chrome folders (1 is a shortcut), one chrome.rdf file and two userchrome-example.css files. What is chrome? Why do I have so many? What causes the slowdowns?
The word chrome is a generic term "The basic structural elements used in a graphical user interface, such as window frames and scroll bars, as opposed to the content."

The chrome files you have found are needed for Firefox to function correctly. Please do not remove them.
