I tried to use it to prevent Ctrl W from closing a tab, and instead it swapped in another tab and removes the original tab, causing it to function in a loop anytime you press Ctrl W, and leaving you unable to close out of the new tab thereafter. Obviously thats not what I was looking for, and obviously i was trying to "Disable Tab Close". I understand if it was trying to have it swap to another tab instead, but thats not what its doing for me. It doesnt work, and it also breaks your tab functionality (if you can make it so that it actually disables tab close, i will appreciate it, but right now, its near-malicious in how it behaves.

Thank you. So helpful to prevent accidental closing.
New users: This does NOT work through the toolbar. Instead, (once installed)
- right-click at the tab/page title (in the tab bar that lists the tabs open in the current window), and choose
- "Disable Tab Close" from the drop down list.

Extension safety
Risk impact
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, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
Disable Tab Close requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
- Critical ****** ****** ** ******* ***** ***** *** ** **** ** ***** **** ******** ****** *** ******** ********** * ******* ********
- Medium ******* ***** *********** ***** ****** ********* *** ***** ********* **** **** ************** *** ********
Risk likelihood
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.
Disable Tab Close is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
Risk likelihood analysis details
- High This extension has low user count. Unpopular extensions may not be stable or safe.
