Thе video below is in Webm container with VP8. I could play it but not seek through it. When I seek forward it waits until the whole chunk between the previous and current position is download.

Everything was working fine with Firefox 39 but now with Firefox 41 it is not.

The seek works on other browsers (Chrome, Chromium, Microsoft Edge) but not on firefox.

There are no plugins in the installation that I use. I have tried the Troubleshoot before posting the question and after posting the questions, but in both cases it does not work.

The progressive download works correctly for ogv files but firefox chooses do download webm files and it does not work there.

Just check the link with the video.

Is there another place I could ask this, because it seems like a bug but I got no response?
