no MP4 YouTube videos anymore (just FLV) Rated 3 out of 5 stars
I can no longer get MP4 videos showing up next to the animated icon on YouTube. Tried all 4.7 releases right down to version 4.6.5 of Video DownloadHelper. Version 4.6.4 and earlier claims it is not compatible with my version of Firefox (latest on Windows XP Service Pack 3, 32 bit), so I couldn't go any further there.
Now I can't even remember which version I uninstalled for this latest version, but it just goes to show you that newer isn't always better. I may just try an older version of Firefox with an older version of DownloadHelper to restore functionality (I manually update things and I am regretting I even updated both Firefox and Video DownloadHelper now).
