java script pop up windows
Using Firefox (tried Safari and Chrome) and I keep getting pop up ads and redirects to other advertisement websites. Why and how can I fix it?
MacBook Pro, OS X Yosemite (10.10.4), Java Script warning popups
First try
Remove unwanted adware that displays pop-up ads and graphics on your Mac
Next:

You can also get plug-ins/extension for the browsers that allow you to block Javascript and it ask you to enable it for sites you want Javascript.
I think for FireFox it is called NoScript
