WINDOW TABS LOCK:
click button to turn lock onPURPOSE: Stop accidental closure of multiple tabs.
HOW TO USE: 1.) Turn it On. 2.) Keep this tab open.
When asked "Leave site?", click "Cancel" or hit the escape button. This will prevent the window from closing and losing other opened tabs.
This simple trick protects all other tabs inside the same browser window from being closed by accident.
CRITICAL NOTE: Stop Chrome from de-activating this tab.
1.) Open: Settings > Performance > General > "Always keep these sites active".
2.) Add "savanttools.com" to the list.
URL for the settings: chrome://settings/performance
WHY: Chrome browser has a "memory saver feature" that will put older tabs into an inactive status, sort of like a sleep state for tabs. If this page is inactivated by Chrome, then it will not work as expected.
DETAILS: Without a Window-Tabs-Lock, if you accidentally close a web browser window, Chrome will not warn you. Chrome browser will happily close dozens of tabs inside the window without confirming that you really want to do that. With this Window-Tabs-Lock, you will be warned before the window containing it can be closed.
This tool is designed for the Google Chrome web browser, but it might also be useful for other browsers such as Firefox and Microsoft Edge.
Additional tip: If you close a browser window by accident, try this to recover lost tabs:
Open: 3-dots menu button > History > Recent tabs.
If you don't recover the window immediately, this method may not work.
The concept of this browser-tabs-lock page might also be referred to as a "session saver" or "tab saver", but this web page cannot actually see any other open tabs and, therefore, it cannot literally save a session. It is just meant to stop you from accidentally closing the window that contains your "session".
There are other solutions that potentially do this better, such as the "Chrome Close Lock" extension. However, browser extensions, addons, and UserScripts all require you to trust the creator. Chrome extensions and similar often have the ability to do unsafe or malicious things. This web page is very simple, entirely client side, and self-contained within one tab. It can not do anything unsafe.
