Not only this extension will let you chose website you would like to display each time you open a new tab, it also will reduce RAM usage as well. The size of extension is only 6k
my new tab is blank - so why open another site which uses more memory? what is your purpose? concerning new tabs or fast dial chrome is a pain.
The size of an extension package has little to do with the amount of memory it uses when running. I could create an extension which package size would be much smaller than this one and yet consumes massive amount of memory and CPU.
