The browser extension and desktop app are two parts of one workflow. The extension finds eligible downloads; the local native bridge passes the selected task to Flux. Installing only one part can leave the browser button visible while the desktop handoff fails. Use the current desktop and extension packages together.
The setup sequence
- Get the Chromium extension package from the Flux GitHub release.
- Follow the release’s extension-loading instructions for your browser.
- Enable Flux and grant the requested site permissions.
- Open the desktop application once to register or repair the bridge.
- Refresh the page containing the file or video you want to capture.
What the media button does
The floating HUD offers supported media choices and passes your selection to a separate Flux approval window. You can dismiss the button with its close control, hide media buttons from the extension popup or close the opened choices by clicking outside. It is a capture interface rather than a promise that every player or protected stream can be saved.
If a download stays in the browser
Check whether interception is enabled, whether the extension has access to that site and whether the desktop bridge connects. Use Settings → Browser integration to repair a missing registration. If another manager such as IDM is active, review its automatic capture preference so two applications do not claim the same download.
Browser-store distribution and local GitHub packages are different installation routes. A native-host registration is not a Chrome Web Store listing, and it cannot make an unsigned extension store-approved. The project’s browser-distribution guide documents the actual route available for each release.
Keep the test small
Verify handoff with a normal file, then test accessible media you are permitted to save. Confirm the destination and selected format before starting. If the source needs an authenticated browser session, keep the source tab available so permitted session refresh can work when supported.
NEW IN FLUX 2.5
Browse detected media, page links and queued transfers in separate tabs. Check the desktop connection and choose a light, dark or system theme for the popup and extension settings.
The slimmer video toolbar follows expanded and fullscreen players. Drag it, close it or hide it from the extension settings.
On Windows, open Settings → Updates → Check for updates. On Linux, install the new RPM. For GitHub-installed extensions, replace the old unpacked extension with 2.6.6 and refresh open tabs. The free Flux desktop app is also required.
The Chrome Web Store submission is under review. Until it is approved, install the browser extension from the official GitHub release.
