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('browser.helperApps.neverAsk.saveToDisk', "application/csv"), it still doesnt work, I have tried everyt .csv related MIME but doesn’t work, is it possible to either click save as radio button and then click ok on the dialog or disable it entirely.

    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:

    Chrome developer tools mime type
