Thamy Them (ID: 00000063c6c5e237) Voted 3 ★ - Updated 06/06/2022 It works fine but There's no information in the privacy practices tab . So i am still looking for another one similar to this one . or get rid of chrome and use fairfox instead . chrome must be sued for making lose of many many works for millions of people by avoiding to add this important and reqired action in confirming the sudden shut down of their browser.

Aditya M (ID: 00000050b304ae5b) Voted 3 ★ - Updated 06/17/2021 I'm concerned that there's no information in the privacy practices tab. Functionality 'works', but you can't un-lock a page once you lock it from closing, which might be required by someone's workflow. I think Chrome should support this feature natively as web apps are so critical to peoples' workflows now.

Stan Merezhko (ID: 0000008cc07701ca) Voted 5 ★ - Updated 04/22/2021 I spend many hours a day working in a browser app and I hate it when I close it by accident. This exprenstion is a lifesaver! Yes, I still need to re-confirm it every time I restart chrome, but it's a small price to pay.

Jack Z (ID: 000000d7cc3f216e) Voted 3 ★ - Updated 10/13/2019 It works as described, but the setting doesn't last through a confirm cycle: once you've marked a page for closure confirmation, you need to confirm if you close that page. After you've confirmed and closed it once, it is no longer marked for confirmation. So it won't serve my purpose: prevent exiting Chrome by accident. To accomplish this I'd have to open a tab and mark it for confirmation every time I start the Chrome browser. I'd never remember to do this until it's too late! I'm reluctantly removing the extension.
