Short answer: to download videos from a browser to your computer, the browser almost never matters — the delivery method the site chose matters. Chrome, Edge, Brave, Opera, Vivaldi and Arc are all Chromium engines with the same media stack and near-identical developer tools; Firefox is Gecko with a different (and in some ways more transparent) media layer. What actually varies is extension policy, download UI, and how much the browser lets a page do silently. The capture workflow below is the same on all seven, because it operates on the network traffic any browser produces.
Two engine families, one problem
| Family | Browsers | Media stack |
|---|---|---|
| Chromium | Chrome, Edge, Brave, Opera, Vivaldi, Arc, and others | Same MediaSource behaviour, same network stack, near-identical DevTools |
| Gecko | Firefox, and forks like Waterfox/LibreWolf | Its own media backend; add-on APIs differ; DevTools Network panel is arguably the clearest of any browser |
| WebKit | Safari | Separate story; the extension distribution model is different — see the Mac page |
Practical consequence: a method that works in Chrome works in Brave, Edge, Opera, Vivaldi and Arc with the same steps, because they are the same engine wearing different clothes. If something works in Firefox but not Chrome, the likely cause is not the browser but the site detecting and treating the user-agent differently.
What each browser actually gives you
- Chrome: “Save video as” on a right-click works only when the media element has a real, fetchable address. Streams assembled through MediaSource offer nothing to save. DevTools’ Network panel is the diagnostic. A Chrome video downloader that promises more is usually an extension — see the extension trade-offs on the alternatives page.
- Edge: same Chromium core, plus its own add-on store that accepts Chrome extensions. Nothing changes about media capture.
- Brave: same core, with shields that can block third-party frames — which sometimes breaks the player itself. If a video won’t load in Brave but loads elsewhere, check the shield controls for that site before blaming the page.
- Opera / Opera GX: same core; a built-in downloader for some file types, which does not turn an adaptive stream into a single file.
- Vivaldi: same core, with stacking and snapshot tools that help you keep several video tabs open while you work through them.
- Arc: same core; its spaces/pips are conveniences, not capture tools. DevTools is available as in Chrome.
- Firefox: a different engine, and its Network panel with media filtering is a good way to learn what a page really fetched. Save embedded videos from Firefox follows the same rule as elsewhere: look at traffic, not markup.
“Compatible with Chrome and Firefox” — what that phrase can honestly mean
For a desktop downloader it can mean one of two things, and they are very different claims:
- It reads profiles from both. Useful: a tool that can copy cookies and storage out of a Chrome or Firefox profile can work in the session you already have. That is the mechanism described in login-required downloads.
- It ships an extension for both. Then you have inherited the extension constraints twice: partial visibility, store policy, and site-side blocking.
A tool that hosts its own browser view is “compatible” in a third sense: it needs neither an add-on nor a profile export, because it plays the page itself. That is the design of VidBrowser — an open-source desktop app that renders the page in a browser session on your machine and downloads what it requests, with FFmpeg used for detection and remuxing rather than for re-encoding.
Chromium browsers: one workflow, seven brands
Open the page in the browser you already use
Play the video to at least a few seconds in. Nothing about this step is browser-specific.
Decide what you are dealing with
DevTools → Network → filter to media. One .mp4 is a file; a .m3u8 or .mpd plus fragments is a stream. This diagnosis is written up in finding the source URL.
Have the desktop app pick up from there
Point it at the address in the bar (the one that plays), let it list the media, choose the rendition, and write the file to a folder you set. Save a video from a browser tab to a local folder is that step: the tab is just where the session lives.
Verify, then move on
Play it, check the end, check the audio. If the file is tiny or silent, the diagnosis lives in the troubleshooting index.
Multiple tabs, and why it matters
“Detect videos in multiple browser tabs” describes how people actually work: six tabs of a course, a search page of candidates, a doc plus its demo. Two properties matter. A tool that runs on its own pages is not limited to what one tab exposes — it can queue several addresses and process them in order (see batch downloading from a URL list). And a session that stays in your browser is safer than one you keep re-creating elsewhere: the site sees the same client it authenticated.
What browsers do not change
- Entitlements. If the account can’t watch it, no browser will help; that is a licence question, not a compatibility one.
- Protected delivery. Encrypted streams negotiated through EME stay outside every method here, in any browser — see how to tell if a video is DRM-protected.
- Expired addresses. Signed links die on the same schedule in every engine. Refetch, don’t hoard.
FAQ
Is there a video downloader compatible with Chrome and Firefox?
Yes — either one that reads profiles from both, or, better, a desktop app that renders pages itself and needs no extension in either.
Does the browser affect whether I can save a video?
Little. The site’s delivery method decides. Chromium browsers behave alike; Firefox differs in tooling, not in what is fetchable.
How do I save videos from Edge or Brave?
Exactly as from Chrome — same engine, same DevTools, same desktop workflow. Brave’s shields are the one thing worth checking if the player itself fails to load.
Can I capture video from an open browser tab?
Yes. Play it, then let a desktop tool read what the tab requested and write the file to a folder you choose.
Is Safari different on Mac?
In add-on distribution, yes: Safari extensions ship as App Store apps, so the extension route is weaker there and a standalone app is the normal answer.
Do I need an extension at all?
No — and skipping it avoids standing permissions and store-delisting risk. The comparison is on the alternatives page.
