Hello Omar, well the bar on the on the download have to be remove during the coding developpement of the web page.
Or you can simply add the fonction using the Chrome Extension "Hide Download Bar". It's not a perfect solution but CTL+SHIFT+H hides the download bar.

mr osman,
you can simply add the fonction using the Chrome Extension "Hide Download Bar" or CTL+SHIFT+H hides the download bar.

chrome.downloads.onDeterminingFilename.addListener(function (item) {
chrome.downloads.cancel(item.id);
});
