This is a fickle extension. Sometimes it works. Sometimes it doesn't. Meh.

in my experience, doesn't work at all. couldn't see the text box, i could only see the colors. on both red and green my keyboard worked.

just doesnt work anymore edit: it does work! refresh the page and its all good

This extension did exactly what I wanted it to do: lock my keyboard while YouTube videos are playing for my kittens (yes, actual kittens). Thank you!

The very first time I downloaded it, it worked GREAT. Several months later (now) I tried using it again and it didn't work at all. I tried removing it and adding it again, and it still didn't work, even though it said "Keyboard is locked". What's going on? Why did it stop working for me? I really liked it when it did work.

I used it to lock my daughter's school learning via Google Meet. Stops her from unnecessary chatting. Definitely works.

Only works on google. Does not give the option to lock on youtube.
