The first time I tried to viewing a video using Firefox 2.0.0.12 (on Unbuntu 7.10)I was prompted to install a plugin. My choices were the Adobe Flash Player and Gnash . I decided to use the Gnash Player. Unfortunately I was then not able to play any videos. The video control was blank. I could right click on the video control and click play but nothing would happen.
I thought this would be simple enough to fix. I would simply go into the fire fox addins and remove the gnash player. The only way I could remove the Gnash player was to uninstall it using the Synaptic Package Manager. You can find this by select System>Administration>Synaptic Package Manager. Once you do this just do a search for gnash :
Then click on gnash-common package and select Mark for complete removal:
Now that Gnash is uninstalled you can open up FireFox and browse to a site that contains a video (e.g. You Tube) . When you try to view the video you will be prompted to install a flash player. Chose the Adobe Flash Player and wait for it to install.
