As a workaround, you can go to Solution Properties -> Configuration Properties -> and uncheck the Build action for the setup Project (then close and reopen visual studio).
Later you reactivate it only when setup creation is required.
Question
First of all, they took away the default setup project and give us a 3rd party tool to package ( maybe its a topic for a separate forum), but visual studio keeps opening a new tab with the flexera customer support page(with an irritating javascript error) whenever i have a 'error' in my code .
how can i disable this feature ?

OTHER TIPS
Another workaround. Right-click on setup project and choose Unload Project. When you want to build setup again, use Reload Project.
Not a solution, but another workaround. Edit your hosts file and point that website to localhost. Gets rid of the popups, but not the extra tab in Visual Studio.
1) Run this:
notepad C:\Windows\System32\drivers\etc\hosts
2) Add this text and save the file:
# To get rid of the annoying javascript error popups in Visual Studio
# Example problem URL: http://flexerasoftware.force.com/SupportKBList?searchString=-1014
127.0.0.1 flexerasoftware.force.com
3) Run this:
ipconfig /flushdns
4) Close re-open Visual Studio.
My favorite workaround (10 seconds but must be re-done after each VS2013 restart):
1) Right click the tab and click [Float]
2) Minimize the window and put it in an unused corner of VS 2013
