I don't see any major issue in your code. But while you setPreference for the FirefoxProfile Class do remember to add all the relevant Multipurpose Internet Mail Extensions of CSV type files referred in this site .

Here is your own code block with some simple tweaks added to it:

String downloadFilepath = "C:\\Utility\\OP_Resources\\MozillaFirefoxDownload";
System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
FirefoxProfile Profile = new FirefoxProfile();
Profile.setPreference("browser.download.dir",downloadFilepath);
Profile.setPreference("browser.download.folderList",2);
//neverAsk - saveToDisk - CSV        
Profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/csv,application/excel,application/vnd.ms-excel,application/vnd.msexcel,text/anytext,text/comma-separated-values,text/csv,text/plain,text/x-csv,application/x-csv,text/x-comma-separated-values,text/tab-separated-values");
//neverAsk - saveToDisk - ANY       
Profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/xml,text/plain,text/xml,image/jpeg,application/octet-stream");
Profile.setPreference("browser.download.manager.showWhenStarting",false);
//neverAsk - openFile - CSV
Profile.setPreference("browser.helperApps.neverAsk.openFile","application/csv,application/excel,application/vnd.ms-excel,application/vnd.msexcel,text/anytext,text/comma-separated-values,text/csv,text/plain,text/x-csv,application/x-csv,text/x-comma-separated-values,text/tab-separated-values");
//neverAsk - openFile - ANY
Profile.setPreference("browser.helperApps.neverAsk.openFile","application/xml,text/plain,text/xml,image/jpeg,application/octet-stream");
Profile.setPreference("browser.helperApps.alwaysAsk.force", false);

I have verified my code on this site and Microsoft site as well and seems to me works fine.
