Running PHP debug session in Netbeans always opens as a new tab in browser (I use Chrome and Firefox).
How to force browser (or Netbeans) to run the session in the same browser tab, so I do not have n open tabs with the same url for debug?
I'ts really a browser issue, not a Netbeans issue. The browser command line provides no mechanism for using a particular tab. Generally, the only choice you have is whether or not to open a new instance of the browser.
I have worked around this in the past be adding a meta refresh tag to periodically update the display.
To prevent this go to
Project->Properties->Run Configuration->Advanced->Do not Open Web Browser
