Is there a Facebook video downloader that works in Firefox?

Yes. FB DownS is a website, so it runs in Firefox with no add-on at all. Paste the copied Facebook link at /facebook-video-download, pick a quality, and Firefox saves the MP4 to your Downloads folder.

Does it work in Safari on a Mac?

Yes. Safari saves the file through its normal download manager and shows a progress ring at the top right. If Safari asks whether to allow downloads from the site, click Allow and the save completes.

Where do Safari downloads go on an iPhone?

Into the Files app, under Downloads in iCloud Drive or On My iPhone depending on your Safari settings. To get the video into your camera roll, open it in Files, tap Share and choose Save Video.

Does it work in Microsoft Edge?

Yes. Edge saves to your Windows Downloads folder and shows the file in its downloads flyout. Press Ctrl+J at any time to see your full download history and open the saved video.

Are there browser extensions that help download Facebook videos?

Some exist, but FB DownS does not offer one for any browser. Downloader add-ons typically need permission to read and change data on the sites you visit, and a plain web page saves the same file without that grant.

Why does Edge say the download is blocked or unverified?

That is Microsoft Defender SmartScreen doing a reputation check on a file it hasn't seen often. Open the downloads flyout, click the three dots beside the item and choose Keep to finish saving the MP4 you requested.

Safari asks whether to allow downloads from this website — is that normal?

Yes, Safari asks that the first time a site tries to save a file. Click Allow and the download proceeds. You can review or change it later in Safari's Settings under the Websites tab.

How do I change where Firefox saves my videos?

Open Firefox Settings, go to the General panel and find Downloads. You can set a different folder or switch on "Always ask you where to save files" so you choose a destination for each download.

Do I need a different tool for each browser?

No. It is one website and it behaves the same everywhere. Only the browser's own download manager differs — where the file lands and how you're notified that it arrived.

Does it work in Brave, Opera or Vivaldi too?

Yes. Any modern browser that can display a web page and save a file will work, including Brave, Opera and Vivaldi. The steps are identical; check that browser's download list to find the saved MP4.

Can I download Facebook videos in HD in Firefox or Safari?

Yes, when the uploader provided an HD version. The maximum is the best merged file Facebook publishes for that video, which is usually 720p HD, and that limit is the same in every browser.

Can I download several videos at once?

No. FB DownS handles one video at a time by design — there is no batch queue, no scheduling and no API. To save several clips, repeat the paste-and-download step for each link.

Does the file pass through your servers?

No. The video transfers directly from Facebook's content delivery network to your browser, so nothing is stored or re-hosted on our side and no download history is kept.

My download disappeared — where is it?

Check the browser's own download list before retrying: the toolbar arrow in Firefox, the progress ring in Safari, or Ctrl+J in Edge. If you changed the default save folder previously, look there rather than in Downloads.

Is it legal to save Facebook videos in these browsers?

Saving public content or your own uploads for personal offline viewing is generally fine, and the browser you use makes no difference. Redistributing someone else's video or using it commercially without permission can infringe copyright.

Facebook Video Downloader for Firefox, Safari and Edge

Yes, you can download Facebook videos in Firefox, Safari and Edge exactly as easily as in Chrome, and you need no add-on for any of them: copy the video's link from Facebook, paste it into the FB DownS downloader at /facebook-video-download, choose a quality, and let the browser's own download manager write the MP4 to disk. The website part is identical everywhere because it's just a web page. What changes is the last ten seconds — where each browser puts the file, how it says the download finished, and which safety prompt it shows first.

That final stretch is where most confusion happens. People assume a download failed when Safari quietly finished it, or hunt for a file Edge saved somewhere they never picked. This guide walks through each browser's behaviour so you know what to expect and where to look.

The quick answer

Every modern browser can request a video file and save it locally — that is core browser functionality, not a Chrome exclusive. FB DownS is a plain website, so it runs the same in Firefox, Safari, Edge, Opera, Brave and Vivaldi. There is no browser-specific build to hunt down, no add-on gallery to visit, and no login. The tool is free and carries Google AdSense advertising on the page, which is what keeps it free.

One thing is the same everywhere: the video transfers directly from Facebook's content delivery network to your browser, never through our servers, and we keep no record of what you downloaded. Your browser's own download manager does the saving — which is exactly why the per-browser differences below are the only ones that matter.

The steps, identical in every browser

Open the Facebook post in Firefox, Safari or Edge and make sure the video plays.
Click Share under the video, then choose "Copy link" to copy the URL.
Open a new tab and go to /facebook-video-download.
Paste the link into the field — Ctrl+V on Windows and Linux, Cmd+V on macOS.
Press Download and wait for the available qualities to appear.
Choose HD or SD, then confirm the save when your browser asks.
Open your browser's download list to check the file and play it.

Firefox: the download arrow and library

Firefox saves to your system Downloads folder by default and animates a small arrow in the toolbar when a file arrives. Click it for the recent-downloads panel, or open the full Library with Ctrl+Shift+Y (Cmd+Shift+Y on macOS), where you can play the video or reveal it in your file manager.

If you'd rather choose a folder each time, open Settings, find Downloads in the General panel, and switch on "Always ask you where to save files." Firefox's strict tracking-protection mode can occasionally interfere with a page's scripts — if the downloader page looks broken, click the shield icon in the address bar and disable protection for that site only.

Safari on Mac and iPhone

On a Mac, Safari shows a download progress ring at the top right and stores files in Downloads unless you change it in Settings under General. Safari is stricter than most browsers: the first time a site tries to save a file you may see a prompt asking whether to allow downloads from that website. Click Allow and the save continues.

On iPhone and iPad, Safari saves into the Files app, usually in iCloud Drive or On My iPhone. The video will not appear in Photos automatically — open Files, find the MP4 in Downloads, tap Share and choose Save Video to move it into your camera roll. That extra tap catches out a lot of people who assume the download failed.

Microsoft Edge and its download flyout

Edge behaves much like Chrome under the hood but presents downloads in a flyout panel from the toolbar rather than a bottom shelf. Files go to your Windows Downloads folder by default, Ctrl+J opens the full history, and you can turn on an ask-each-time prompt from Settings under Downloads.

Edge also runs Microsoft Defender SmartScreen, which occasionally flags a file it hasn't seen often before. The download then shows as blocked or unverified rather than failed: open the flyout, click the three dots next to the item, and choose Keep. It's a reputation check on the file, not a verdict on the video — but only override it when you know what you asked for, which here is an MP4 you just requested.

Why there is no add-on for any of them

There's no FB DownS add-on for Firefox, no Safari extension and no Edge add-on, and that's a deliberate choice rather than a gap in the roadmap. A downloader add-on needs permission to read and change the pages you visit in order to spot a video, and that permission applies broadly across your browsing, not just on Facebook. Since a normal web page achieves the same download without asking for anything, the add-on would add permissions without adding capability. Plenty of add-ons in this category are maintained carefully — the point is only that the permission model is the cost, and here it buys a keystroke you can save with Ctrl+V.

Where the file lands in each browser

Firefox on Windows, macOS or Linux: the system Downloads folder; toolbar arrow, or Library at Ctrl+Shift+Y / Cmd+Shift+Y.
Safari on macOS: the Downloads folder; progress ring at the top right of the toolbar.
Safari on iPhone or iPad: the Files app, under Downloads in iCloud Drive or On My iPhone.
Edge on Windows: the Downloads folder; downloads flyout in the toolbar or Ctrl+J for full history.
Any of them: turn on "ask where to save each file" in settings if you want to choose the folder yourself.

When a browser blocks or loses the download

The browser blocks the save

Safari may ask permission to allow downloads from a site, and Edge's SmartScreen may hold an unfamiliar file. Both are one-click overrides: Allow in Safari, Keep in Edge's flyout. Firefox rarely blocks video files, but an aggressive content blocker can stop the page's scripts — pause it for that tab and reload.

You can't find the file afterwards

Open the browser's own download list first: the arrow in Firefox, the ring in Safari, Ctrl+J in Edge. Each list can reveal the file in your file manager. If you previously changed the default save location, check that folder rather than the standard Downloads directory.

The pasted link isn't recognised

Facebook uses several URL shapes — fb.watch shortlinks, /reel/ addresses, /watch/?v= permalinks and /share/v/ links. If a shortened share link fails, open it in a tab first, let it resolve to the real video page, then copy the final URL from the address bar and paste that instead.

HD isn't as sharp as you hoped

The ceiling is whatever Facebook publishes as a merged file for that video, which in practice is usually 720p HD rather than true 1080p or 4K. That limit is identical in every browser, so switching from Firefox to Edge won't produce a sharper copy — the source is the constraint, not the download manager.
