Download Manager with Browser Integration: Chrome, Edge, Firefox, and Safari
The browser is great at finding links; a download manager is better at downloading them. Browser integration connects the two so you never copy a URL by hand.
What browser integration does
An extension watches for downloadable links and media, then offers to send them to the download manager instead of the browser's basic downloader, which has no real queue, no acceleration, and limited resume. The browser finds the link; the manager does the heavy lifting.
Chrome and Edge use the same extension
BoltFox publishes one Chrome Web Store extension that also installs on Microsoft Edge, because Edge is built on Chromium. You install it once and it works the same way in both browsers.
Firefox add-on
A dedicated Firefox add-on on addons.mozilla.org captures links the same way under Firefox's own permission model, so Firefox users get the same one-click hand-off to the app.
Safari is built into the macOS app
On macOS, the Safari extension ships inside the BoltFox app, so there is no separate download. Enable it in Safari Settings, Extensions, and captured links hand off to the app. Both the .DMG and Mac App Store editions of BoltFox include it.
No duplicate downloads
A well-behaved extension cancels the browser's own download once the manager takes over, so you do not get a stray Save As dialog plus a half-finished file sitting in your Downloads folder.
Privacy: capture stays local
Link capture and hand-off happen on your device, between the extension and the local app. BoltFox does not upload your browsing or download history to do its job.
