FlashVideoReplacer version 1.0.6 has been released today and is available for download through GitHub. It will be available through Firefox's extensions update and through the Stable Channel as soon it gets reviewed by Mozilla editors.
The most important change is the increase of video resolution on all YouTube quality settings. I have received some complains about video quality, so I raised the maximum limit. Now the LOW quality setting will play the best resolution available, up to 480p, the MEDIUM quality setting will play the best resolution available, up to 720p and the HIGH quality setting will play the best resolution available, including original HD higher than 1080p.
You can test the extension with Sintel HD video, which renders incredible video quality when setting the extension to HIGH quality YouTube videos.
The extension also has some feedback alerts now, which will notify the user if some incompatible extensions are installed and will notify the selected video resolution on YouTube.
