Following up with https://bugzilla.mozilla.org/show_bug.cgi?id=1732446#c3, I've realized what was actually rubbing me wrong in regards to Alt+F4. Alt+F4 to my understanding is generally defined as close imediately and I would read that as bypass any confirmations. Although Alt+F4 is defined for Linux [here](https://docs.google.com/document/d/182DIE0qMCRv6drA8enNUbe3ZmwYNc6uVerRfOgjDGOI/edit#bookmark=id.e0c9fg5mblf8) to generate warning on default Fx94 configs (browser.tabs.warnOnClose on false) it doesn't. The behavior for Windows is not specified in the said document, but currently Fx94, no warning will be fired for Alt+F4. I believe both for Windows and Linux, the current behavior with default settings(browser.tabs.warnOnClose on false) is the correct one : do not warn. Switching the (browser.tabs.warnOnClose on true), Alt+F4 will generate close warning, which I personally wouldn't expect it to do, since it should close imediately, regardless of the state of the browser.tabs.warnOnClose value. Please note that the behavior of Alt+F4 before bug 1732445 would've warned.
