I am noticing that the Login Page of Facebook appears with Mark’s picture in Firefox. The same does not happen in IE10/Chrome. Is this the same behavior for everyone?

Considering the Internet Bandwidth/Plans/Cost in India, I prefer to download favorite YouTube videos for Offline Viewing. This helps me enjoy the videos without buffering. To achieve this, I am using Video Download Helper plug-in on Firefox. Since past few days, when I download the video using Download Helper, it just downloads zero bytes file.

The above problem was acknowledged by Video DownloadHelper website, stating the following statement:
September 14th 2012 YouTube issue – We are aware of the problem that occurred on Sept 14th (13th if you are in the US). This is due to some changes YouTube just made. We are working hard at solving the issue. Please, give us a little bit of time and refrain from downrating the addon.
In fact, the Developers of this add-on provided a quick work-around by providing a beta version 4.9.10b2 of plugin for users. You can access this beta version from this link. This helped many users to fix the zero bytes download problem.
Flash Update:
Just after writing above post, when I restarted my Firefox, my DownloadHelper plug-in got upgraded to final version 4.9.10
Thanks to the Developers of this add-on to provide a quick fix for this problem. I am now able to download the YouTube videos without the zero bytes problem.
