Chrome Refresh Guard is a free browser extension developed by kynetiv. This add-on falls under the category of Browsers, specifically Add-ons & Tools. Its main purpose is to guard against navigation and refresh actions on the currently inspected page in Chrome.

To activate Chrome Refresh Guard, simply visit the devtools window and navigate to the "Refresh Guard" tab. Once activated, this extension will prevent you from navigating away from the current window or refreshing the page. If you attempt to do so, a generic dialog popup will appear.

In the dialog popup, you have two options:

• Select "Leave" or "Refresh" to disable the Refresh Guard, allowing navigation and refresh actions.
• Select "Cancel" to block the navigation or refresh, keeping you on the current page.

This extension is particularly useful for UI development and making local modifications to the current window in Chrome devtools. It also serves as a handy tool if you dislike websites or other extensions automatically navigating you away.

In terms of future improvements, the developer has outlined a roadmap that includes enabling the extension from the status bar button and preventing popstate or SPA route changes that don't trigger a navigation.

Overall, Chrome Refresh Guard is a basic yet effective extension for protecting your currently inspected page in Chrome.
