Shockwave flash plugin not working at all!! HELP

Question

So, here is my problem, I have windows 8.1 64bit and running the latest mozilla firefox.
I've had a lot of problems with flash player (32bit), videos not working properly, loading very slow.. (i have fast internet, working good) then i updated flash and it totally stoped working.
Resetting Firefox does not work for me. Flash player is not working at all, so i had to uninstall it. i uninstalled both flash player and shockwave player. i tried having only flash player - still not working.
I've already tried these too:
-Uninstalling and re-installing flash player
-Uninstalling and re-installing in Safe Mode
-Turning off hardware acceleration in both Firefox and flash player
-i have updated all drivers on my computer
Still not working at all! WHY?

This add-on will prevent Flash from running on the web page until you want.

Never be annoyed by a Flash animation again! Blocks Flash so it
won't get in your way, but if you want to see it, just click on it
If you have problems with current Shockwave Flash plugin versions then check this:
* see if there are updates for your graphics drive drivers
'''https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration'''
* disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
