TabReturn
Simulate 'keep browser open when the last tab is closed' behavior.
TabReturn: Keep Your Browser Open - Edge Add-On
TabReturn is an Edge browser extension that ensures your browser remains open, even when the last tab is closed. It works by ensuring there are always at least two tabs open; this means if you close down to one, a new tab automatically appears. You can choose between having the second tab as a normal or a pinned tab. Implement this add-on to avoid accidental closing of your browser when closing the last tab.

Add-on summary
Keep browser open when the last tab is closed. On some browsers it is possible to keep the browser open when the only tab is closed; this extension simulates that behavior. It does this by making sure there are at least two tabs at all time; if the number of tabs drops to one, a new tab is created (either a normal or a pinned tab depending on the condition).
User reviews
不错，能用。最后一个标签页上没有X，通过右键菜单的关闭或ctrl+w都无法关闭。但倒数第二个标签页也关不掉，一旦关掉会自动再打开一个空白标签页补上，因此一直在左边显示两个空白标签页。另外不知是不是版本有改，两个不同的edge窗口，一个中的标签页是可以拖到另一个窗口的标签页中合并了。

chrome商店里的一堆last tab在启动增强模式下要么无效，要么启动浏览器的时候会闪屏一下，这个是最好用的。

很好用，但有一个bug，打开两个窗口后拖动其中一个窗口的标签页与另外一个窗口合并会失败。
