About the browser project
Step 1: Make sure you selected the right game
A search for a Black Ops browser game can lead you to a round-based Zombies project or to a Black Ops II-style deathmatch, and they play nothing alike. For this guide you want the round-based survival option. Use the project's own page to see which host it runs on and whether it is offered as a permitted in-page embed or has to be opened at its original source.
Getting this wrong is the most common reason the rest of the guide seems not to apply: the habits below assume rounds, points and a map you can walk around, none of which a deathmatch has.
