So I have a Mac desktop (not a laptop) and when I open Youtube on Firefox, it freezes the browser and my computer. My Mac is an older 2011 one, but Firefox is up to date and when it does freeze the only fix I found was to restart my computer. Really annoying and I need to know if anyone has a solution???? It doesn't do it all the time, but when it does it is so annoying. please help!

Security Issue: Update your Flash Player Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.

Flash Player Version: 21.0.0.242 Flash Player (Linux) Version 11.2.202.621
