I don't know were to put this ...so I'm putting it here.
I'm trying to download Forge Version 184.108.40.2065 for Minecraft 1.6.4 for Pixelmon 3.0.2 but every time I click on the installer download link I get a gray screen and some dots but the link is still in the bar
It's probably something to do with how your browser is loading adfly links. My guess would either be adblock of some kind messing up, cookies aren't enabled, or maybe clear cache. You could also try opening it in a different browser for a quick check if you have multiple installed.
