Problem with rewinding previews

I have a problem with rewinding audio previews in Firefox 14.0.1.
When I try to rewind track while listening it on main/categories pages it stop playing.
Works fine in ?hrome.

Also a problem. I use only the browser Chrome from Google and there is also very often the problems began to appear when listening to the tracks on AJ. I have not seen a tick to move and the graphic equalizer is not visible, just a black screen. And sometimes it is impossible to rewind the track just starts to play again, even though it is fully loaded into the cache memory

I also noticed, Mozilla used before, now I use Chrome .. have to wait when the slider will move a little and then rewind becomes possible.

Also, lately I’ve noticed that tracks go back to the beginning when I try to FastForward them from list preview.

If I’m not mistaken, I think it’s a caching issue.. The preview.mp3 must be fully loaded in the player before you can jump to another point.. or is it something else?

Problem in Firefox 14.0.1 is reproduced even when preview.mp3 is fully loaded
I’ve also checked it in Firefox 12 – the same issue.

The same problem- Firefox

Previously, this was not on the Firefox / .... Now starts at the begining
