Add-ons cannot prevent tabs from being closed. This add-on restores a tab as soon as it is closed. This causes a page reload. The tab ID will change to a new one. The session information attached to the tab disappears. As a result, add-ons that depend on them may not work properly.
This add-on can only recover it if only one tab is closed. If multiple tabs are highlighted and closed at the same time, they cannot be restored correctly. It may not be possible to recover properly due to a bug in Firefox.
In addition, the add-on can display a dialog box on a web page when a user attempts to close a tab, asking the user to confirm whether to close the tab. However, this feature displays a dialog box not only when you try to close a tab, but also when you try to navigate to another page. For this reason, this feature is less versatile, but may be useful for tabs that never leave from a particular page. For this to work, you have to do something with the page after it is displayed. For example, click once on the page with the mouse. If no operation is performed, the dialog box will not be displayed. This feature does not work on special pages such as addons.mozilla.org and about:*.
Tabs that you want to prevent accidentally closing must be specified in advance. It can be specified using the context menu or shortcut keys. To set shortcut keys, go to about:addons -> ⚙️ Gear icon -> Manage Extension Shortcuts.

Risk impact

Disable Tab Close requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install Disable Tab Close if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Disable Tab Close is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on, especially ones with higher risk impact and/or higher risk likelihood.
