As part of their homework, third year students are required to make three videos through the semester. Most post their videos to Cyworld and send me a link. I am able to access most of these videos with any of the three browsers I use.
Well, until two weeks ago, I used Firefox almost all the time and Explorer the rest. These days, I use Safari (Apple's browser). if it doesn't work, I shut down, change OS and try Firefox. Finally, I try Explorer. Explorer always works but I wonder about viruses and spyware, feeling that Firefox offers more protection. Sarfari apparently offers so much protection I don't see any anti-virus software or concerns.
Anyway, today, I was able to watch all but four videos on Safari. The "mini-hompy"s (a typical Korean abreviation of Mini -homepage) didn't even open. On Firefox, they opened, but the video wouldn't play. Finally, after re-entering my login data manytimes, I was able to get to my emails in Explorer, follow the link and watch the video.
Maybe, for completeness, I should try Chrome, Google's browser.
One other thing about Safari is that when I hover over a link, the link doesn't appear anywhere for me to read. In Firefox and Explorer, I can see the link URL before clicking on it. I like that better.
