I big fan of opera, using since 2016, I found a big problem in opera and opera beta browser (not in opera mini). Whenever i download 1gb or big (i mean big size) file from my isp ftp server or from other internet server, opera browser dont download it, after click on download my browser stuck, lag and sometime crash, but i download the same file from same server by opera mini and its download very very smoothly... Why i dont understand it... Fix it as soon as possible
