I've made a batch file like this:

Code:

@ECHO OFF

REM Opens multiple tabs for firefox

SET BROWSER=firefox.exe

SET WAIT_TIME=2

And I need help to close tabs after opening new ones. The numbers in ...com/g/number?action=join count up to 12259, and I would like to have about 10 of them open at the time. How do I close the tabs automaticly with batch or vbs?
