After I upgraded to Firefox 7 (and 7.01) the Divx web player controls were not available when playing a Divx video on a website and the menu did not come up when I right-clicked on the video. I tried different versions of the Divx web player, including the latest, and the problem remains the same. Also, the video would only play but would not download automatically to the cache in the Divx movies folder on my computer while it was playing like it did before. I have re-installed Firefox 6.02 and everything works fine again.
