Downloading from coomer is easy for me.. I just click on the file.. it takes awhile to open but once it does I click the download button on the bottom right corner of the video.
Now, as far as playing videos go on the coomer site itself, yes, it's been slowing down awfully lately. It's become nearly unplayable since it just keeps buffering throughout. I want to preview videos before I download... I don't wanna download something without knowing how the video will be.
