does exactly what it says. it doesn't take up space in tabs when i pin it. opens for every window. 2023May24 06:46:52pm Update: Didn't work briefly and then works again. Thank God, and thank you!
well I don't know what is wrong with this extension, yes it does what it says, but then it also does a lot more like opens numerous more tabs of the extension and then wreaks havoc on the chrome window. I don't know but it opens in every window I open. I have maybe two open and need too. I work on two different google accounts. stop the extension from opening numerous times. please and then maybe we can move the star bar up
Really useful!
Good extension
Thank you! Now i can't accidentally close my browser!
Is a good extention and it works fine, but now I can not move a tab to my second screen ;-( The "annoying tab icon" shows that you have to click there to really lock your chrome
Simple and only one that works
Excellent. Great workaround for the many times I've accidentally pressed Ctrl+Shift+W and exited all Chrome tabs. Thank you!
fantastica, grazie :)
It works quite good but the background is too scary for me :))
