“CS” stands for “Cookie Safe”.
The main feature is “Deny Cookies Globally” in the CS Lite -> Options menu.
Then, website by website, you can turn them back on.
However, there’s a big disadvantage with this approach:
about 50% of websites will not work. To make them work, i turn on Temporary cookies for that website. They go away when i delete the window or tab. Then i have to turn on Temporary cookies when i return to that website. There’s an add-on bar icon for it
For me, the “Temporary” option disappeared on day. Apparently that’s common, cuz on the CS Lite MOD page there’s a FAQ about it:
Menu item was not displayed
The lost menu item be found in a “Menu Items” tab of “CS Lite Options”. Menu item is restored with a “Add” button.
