Hi, My Firefox and Thundebird internet download / upload speed is slow. I I try with Chrome download speed, it is 7-10Mb up and down. If do same with Firefox, then it is different. Many times it is 0,2Mb, but some time also 5-6Mb Usually upload are faster and it is 5Mb. (Use Chrome, then always faster) It seems to me as random, because many times speed OK and many times not OK. If compare test result with Chrome, then always slow. I use ESET virus control and try to test it without virus control, but same result. Also in Thundebird HTML load are slow. Small picture in e-mail can reach 30 sec. I try to change different things in options, but no result. Can anyone help me with this?
