Tectol? tried to post the link your talking about in english but when copied in English it reverted back to French.
What I can suggest that worked for me is install Google toolbar and it has a translate tab...instantly is translated....yes I know the spam and virus risks but things have changed...not a one...I personally like the autofill bar ha ha. I also clean cookies all the time with CCleaner through hippo as is free....no problems in 2 years. Try it.
