always better to use a download manager, you cannot really do much with the download managers offered by browsers.
Not really--There is ! big exception : !!Opera!! includes the best download manager, even catches torrents, all with high speed!!(Still ID download manager is the very best download manager out there-but its not Freeware) and for catching you tube videos (faster than every Firefox-plugin can) you paste a .js script in one of the opera Folders ,and your all fine.
I just can't understand that a fantastic smooth and snapie Browser like Chrome,wouldn't want to put a fast futured Download-manager to it - Like Opera can and does...
