How to connect to FTP with a web browser
There are several ways to establish an FTP connection to your website files. Usually it is done with the help of an FTP client (program). Read more about this here: How to connect via FTP and upload/download files
In case you do not have an FTP client and you do not wish to download and install one, there is an easier option: You can use your web browser to connect to your site via FTP. To do so, just open the following address:
ftp://username:password@my-best-domain.comIn the above example, replace "username" and "password" with your actual FTP username and password and replace my-best-domain.com with your domain.
If you have problems connecting via FTP, it is possible that your outgoing port 21 is blocked by your local firewall, so you may have to disable it or add an exception first.
