This used to be enabled as soon as I opened chrome but now I gotta click to enable, now everytime a Ad pops up via another window it disables the extension again and I gotta click to re-enable which defeats the purpose of the extension. Could you possibly make this a setting to be enabled on startup like before?
Works good
crash after 2 windows open, Can't uninstall help
Simple and straightforward
useful
This is great, I often accidentally press ALT+F4 and it does so that that doesn't accidentally close Chrome. But I would like it if you made that tab hidden.
