• (2024-04-11) 그린별이구르미: Works!! Even on asp. Thank you so much! (+ is there a Microsoft Edge version please T^T?)
• (2023-03-06) Nick Pike: Does not work on a per-site basis. Only has a global allow/block option. Effectively unusable, don't waste your time
• (2020-02-04) RKB Holding: Perfecto, cumple tal cuál describe. Chrome no tiene opción para bloquear alertas o no lo hace muy bien. Este plugin cumple tal cuál describe. Ojalá no lo mejoren porque así como está, está perfecto, yo lo compraría.

• (2019-03-07) Temyxxa: It's not worked for me. I'm sad.
• (2018-12-22) 테라드: 디시인사이드 개편으로 이 프로그램 더 이상 작동 안됨;
• (2018-07-23) Srihari r.k: kindly provide a feature to block alert whatever url i type
• (2018-07-01) Jeong-hun Sin: It seems to work, but there is one missing feature. You see, the old extension (Better Alert) I was using (but now seems removed) showed the alert message as a banner on the top right. This extension, however, does not show that. I have to click the icon to see the message. But I would not know if an alert is blocked without carefully seeing that tiny icon. It would be better to add an option to show the message on the screen as a banner (but not blocking with an "OK" button).

• (2017-08-14) Storm Holck Olrik: I rate it: 5
• (2017-08-12) Omar Gonzalez: Does nothing. Most basic alert is not blocked even when setting block as default: https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_alert
• (2017-08-10) Guylaine “Jill” Gobeil: IT's OK,
• (2017-08-06) Martin McCormack: It does not work at all. Still getting tonns of alerts, that prevent me from closing the window.
• (2017-07-19) Simply doesn't work. I have tried every combination of options and Facebook is still popping up browser alerts whenever I try to close it. Google should turf this off the web store.
• (2017-07-19) Will Ashley: Doesn't work at all.
• (2017-07-02) Ben Prytherch: It's worked for me so far. I suspect that many of the people saying it doesn't work think it's supposed to be a pop-up blocker. It does not block pop-ups. It blocks scripted page alerts, like the kind that prevent you from closing a browser tab, and hijack your entire browsing session until you click on them.
• (2017-05-26) Chris Harrel: It blocks alert boxes well. Other people think it is meant to block popups, but that is not what it is for. Only 3 stars because this extension causes Chrome to immediately switch to new tabs with I open them with Ctrl + Left Click. I have to uninstall it because of this unwanted side effect. - This issue seems to have been fixed, so I changed the rating to 5 stars.
• (2017-05-25) Leo August: Didn't work at all - even with "block" selected. No icon in address bar, pop-up alerts still appeared.
• (2017-04-16) masamix: 설치할땐 좋았는데 삭제해도 계속 차단기능이 적용되어있음. 트위치 볼때 화면팝업이 안되고 하얀색 화면으로 나올때가 있음
• (2017-04-12) 김상민: The best pop-up blocker
