I am web scraping with selenium and whenever i try to download i file the firefox download/save as file pops up however, even If i apply profile.set_preference(\'brows
you should do two things, first set these three preferences as follows (this is in Java but I guess you manage to translate that to python :-):
profile.setPreference("browser.download.dir", "c:/yourDownloadDir");
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/csv, text/csv");
secondly, you should make sure the download file has the desired mime type. To do that, you can use the web developer tools and inspect the download.
EDIT:
To find out the MIME type open Chrome, press Ctrl+Shift+I (Cmd+Alt+I on Mac OS) change to the 'Network' tab and click your download link. You should see something like this:
Just an additional answer that might help someone, as comments to the accepted answer put me on the right track (thanks!). Another MIME type of CSV you might be dealing with is application/x-csv - that was my case and once I looked it up in the Network tab of the browser, I became a happier man :)
In C#
FirefoxOptions options = new FirefoxOptions();
options.SetPreference("browser.download.folderList", 2);
options.SetPreference("browser.download.manager.showWhenStarting", false);
options.SetPreference("browser.download.dir", "c:\\temp");
options.SetPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv");
