Why isn't flash player plugin working on Mozilla browser?


I have tried to download it and it doesn't work, when I do it says the download timed out at about 40%... I can't even watch videos or anything. YouTube doesn't work at all. What's going on?

YouTube gives the option of using HTML5 try that as a workaround.

Note Flash 11.3 on Firefox Windows has been causing problems for a couple of weeks,some users have needed to downgrade to Flash 11.2 or the secure FlashPlayer 10.3 Developers from Firefox & Flash are apparently supposed to be working on the issue.

Useful links, for those wishing to know more about the current problems with FlashPlayer, especially when using FlashPlayer 11.3 and possibly other downloading or recording software
