I want to use Chrome Close Lock default as ON please change it.
Works wonderfully.
Does what it's supposed to. It can't do it automatically without interacting with the browser for security reasons. This won't be able to be changed permanently because it would be an exploit that google would immediately fix.
Please change these pictures! They are annoying. And it should be better if it starts to function directly, not to wait until we click on it
Completely useless. I have to manually click on it when the browser is open so it starts functioning. And also have to keep a tab open for it to work. Good ideal to a real problem, shame it simply was not done right.
I liked it but I'd love if it starts automatically instead of I have to click on it.
Does not help as every time I start chrome I have to click on these tabs to enable, why it can be automatically enabled if the tab is there :(
Es increíble que un navegador como Chrome no tenga una función tan sencilla como la tiene esta extensión, en cuanto a la extensión es buena y sencilla de usar y un gran alivio para los que somos despistados y cerramos el navegador por error cuando tenemos muchas pestañas abiertas.
TEN TEN nearly as other guy kazuki says DISABLE blinking and its top boyy maybe also let it just run without a annoying tab lol hate it when i open another WINDOWW.
I love it as it works perfectly with my work PC with low RAM :)
