Re: Razer Deathadder Chroma keeps firing without mouse click.

Have you downloaded Razer Synapse for your mouse? If not, see here: http://www.razerzone.com/synapse/ I use synapse with my Razer products and it seems to get everything in sync. 

Out of curiosity, do you have windows 10 and do you have Cortana enabled? She interfered with my Battlefield ( for some strange reason) and when I turned her off, it worked. Post back and let us know if any of this helped or didn't.
