2024-04-05	Firefox user 16483648	Installed this to work with Keevault password manager. It stops logging out of KeeVault unless needed. I created a html launcher to open KeeVault and a blank page when I first open firefox so my logins are ready for use.
2022-07-05	Firefox user 10266452	This plugin requires you to have an open tab dedicated to it in every window you open. It doesn't work without that tab. When you open a new window, this plugin can open a new tab, which covers up your new tab page. Noble effort, but too many sacrifices to be useful.
2021-09-20	Korwin	Для того, чтобы дополнение работало, разработчик предлагает выбрать для вкладки дополнения ("Keep Open 1.0") вариант "Pin This Tab" или "First Position" или "Right Here". При этом, в меню вкладки доступны только варианты "New Tab", "Reload Tab", "Mute Tab", "Pin Tab", "Duplicate Tab", "Bookmark Tab", "Move Tab", "Open in New Container Tab", "Select All Tabs", "Close Tab", "Close Multiple Tabs" и "Reopen Closed Tab" — т. е. ни одного из предложенного. Видимо, дополнение не актуализируется. Кроме того, в принципе неудобно всегда постоянно держать ненужную вкладку. И главное — в Mozilla Firefox 93.0b7 (64-bit) под Microsoft Windows 10.0.19042.1237 дополнение не работает.
2021-02-25	grahamperrin	Fifty gold stars. This extension can help to prevent a horribly lossy issue, which might be impossible for the developer of the extension to fix without an enhancement to Firefox – https://github.com/Drive4ik/simple-tab-groups/issues/716#issuecomment-785488256
2020-06-30	Alek Lunhaj Tanir	Simply as an application buildings, must contains the system should be normal - if user wants to close a tab(last) by click or automatic system and firefox caused to be closed the full apps !! Its unexpected. So an addons is needed to prevent close automatically without hit any keys or option to click. Here, this extension requires manually somethings. But no addons is found for automatic. So searching of that function I have found this extension as only. So, my feedback to be placed here to apply for that function - please make the prevention automatic. So when a last tab closed, it will show a "blank tab".
2019-05-30	Firefox user 15018722	I gave an overly generous 3 stars because I didn't want to bring the review rating way down. There simply is not any help available to help a user make this add-on work. I am not seeing "Leave Page" prompts on any pages or tabs. Also, I don't see any "Activate Protection" options. (Yes, I did go to "About:ConFig" and my settings are correct) I'm using FireFox, ver 67. I'm really grateful that jsher2000 is developing this add-on. It will be extremely useful and appreciated by people like me whom too often accidentally close a webpage. BTW, I didn't just inadvertently stumble upon this add-on, I searched for it because I was hoping such an add-on existed.
2019-05-22	Firefox user 12865189	I version 0.5 with Firefox 66, having multiple windows with the Prevent Window Closing Tab causes a big freeze. Tabs keep running their JS, Youtube keeps playing, but the multiple prompts don't react to mouse clicks or keyboard events. Otherwise, I enjoy using this :)
2019-03-31	Firefox user 13466023	Does not seems to work in 66.0.2 or maybe I have misunderstand something? The extension only protect/prompt me if I try to close a pinned tab. It does not prompt when closing the window or exit Firefox but the pinned tabs will load next time I launch Firefox. The preferences in about:config was set.
2019-01-08	Richard_Odin_Johnson	I know this add-on is still in progress, but as it is it's eminently useful to me, as it prevents me from closing the browser when I mistakenly press alt+f4 instead of alt+4.
