About this extension
This extension provides a simple and reliable way to export the URL of the currently active tab in Firefox to a local text file.

It was created to solve the challenge of reliably getting the current URL via external automation tools, which can be unstable when the browser window is not in focus. This add-on offers a stable alternative by working from inside the browser.

The extension listens for tab activation and page updates. Upon a change, it writes the new URL to a file (firefox_active_url.txt) in the user's default Downloads folder. To ensure the data is always fresh, it also refreshes the file periodically using an alarm. It uses the downloads API to perform the file write operation, overwriting the existing file on each update.

The primary use case is to provide a clean and stable data source for local automation scripts (e.g., Python) that need to know the current browser URL.

Release notes for 1.1
Improved Stability and Reliability

Fixed a race condition where multiple, rapid-fire browser events (like a single page loading) could cause the file-saving operation to fail, requiring a manual retry of the download.

Implemented a "debounce" mechanism. This ensures the save function only runs once after a burst of browser activity has settled, preventing conflicts and making the file-writing process much more robust and reliable.
