👍
It works perfectly for me. Thanks :)
If you accidentally close chrome just press ctrl + shift + T
I love this, it's really helpful. There's only 2 things I don't really like: 1. The images are too low quality, it's really weird. if a better quality image isn't an option i would like an option to choose an image from my computer or from an imgur link. 2. I hate the blinking telling you it's not active, just the triangle would be enough, I find myself locking everytime, even when i dont want to, just so the blinking stops. pls get rid of the blinking or just make so that the "close lock tab" only appear if you click on the app icon on the top right. But it's really useful thanks!
Does not work at all: not for tabs and not for the browser.
It is useless. It does not give the alert, when accidentally closing 1 one tab. This function should be included in Chrome itself. If I fill out a form in Chrome and accidentally close it, I have to start all over. I have to use other browser for that.
Does what it says. Click where it tells you to on the screen and a pop up will ask you if you want to close Chrome instead of just closing, which was happening all the time with my sensitive track pad and was just extremely annoying! I love this, thank you devs!
doesnt work
Love this app. I try to only use keyboard to make myself more proficient on my system, however sometimes when I have to use my mouse I lose place of it and end up accidentally closing my browser playing my music. Major buzz kill. As long as I enable chrome lock on my music window I never have to worry about that happening again. I just wish the lock was enabled by default or there was a way to enable it without clicking it using my keyboard. Hopefully they come up with an update for those two asks or a way to enable it if wanted.
Thank you! Now i can't accidentally close all my Tab
