Flash will not work on Mac OS X 10.5.8

[iamthefederone]

Flash suddenly stopped working for both Firefox and Safari on my Mac OS X 10.5.8. I have tried uninstalling and reinstalling (several times). Would really hate to reset my browsers especially since it is happening to both of them. I have java enabled, I feel like I've tried everything. When I go here it says I have Flash installed (version 10,3,183,43). It's listed under my plugin library but websites still say I need to install Flash. Any ideas?

What websites are failing to load Flash Player for you?  It's possible that they have implemented logic on their side to require a player with a version number higher than 10.3 (though for what reason I couldn't say).

I am trying to watch the on demand videos on the xfinity website. According to the website it says the minimum requirement is Flash 10.0.42
