Just Mozilla’s review process.
I submitted a new version on September 1, that corrects 2 bugs brought to my attention:
1 – it uses the browser cache now, which should make easier to people with slow connections to download content (no more downloading 2 times the same file);
2 – it’s possible to download trailers from Apple website again (I had to change the QuickTime code to avoid Apple’s shenanigans).
I just hope someday Mozilla will make it available to users.
