Download for Google Chrome Also works on Microsoft Edge Desktop browser Firefox Not available Safari

Free browser add-on. You install it yourself in a few minutes (not from the Chrome Web Store). Full beginner instructions are below.

Video-DownloaDR.com functionality:

One video at a time — simple, intentional downloads of content you already have the right to watch.

Video + audio in one MP4

We combine picture and sound into a single file that plays on phones, laptops, and TVs.

Uses your YouTube login

If you can play it in your browser (including Premium), Video-DownloaDR.com can process that same session.

Choose quality

Default is Best. Or pick 1080p, 720p, 480p, 360p, or audio-only for smaller files.

Clear progress

The button shows “Processing…” with a spinner so you know work is happening.

Plays almost everywhere

Defaults to widely compatible H.264 video so the MP4 opens in common players.

Easy on-page button

↓ MP4

Gold button under the video (next to Like / Share) — clearly for the video you’re watching.

How it works

Three simple steps after the extension is installed.

1. Open a YouTube video

Stay signed into the Google/YouTube account that can play the video.

2. Click ↓ MP4

Choose quality (or leave Best) and click Download MP4.

3. Save the file

When processing finishes, your browser asks where to save the finished MP4.

How to install this plugin

You do not need to be a programmer. Follow the steps for your browser exactly. The whole process usually takes about 3–5 minutes the first time.

What you will download: a small zip file named video-downloadr-extension.zip. Inside it is a folder called video-downloadr-extension. That whole folder is the plugin. In Chrome/Edge you will choose the entire folder (not a single file inside it). The folder can live on your Desktop, Downloads, or anywhere you like — wherever you unzipped it is fine.

Chrome instructions Edge instructions Firefox instructions ↓ Download the zip first

Google Chrome Recommended

Works on Windows, Mac, and Chromebooks with Chrome installed.

Download the plugin file

Click the gold Download for Google Chrome button at the top of this page (or the link below).

Your computer will save a file called video-downloadr-extension.zip (usually in your Downloads folder).

Download video-downloadr-extension.zip

Unzip (extract) the file

Find video-downloadr-extension.zip in Downloads, then extract it:

Windows: right-click the zip → Extract All… → Extract
Mac: double-click the zip; a folder appears next to it

You should now have a folder named video-downloadr-extension. You can leave it on your Desktop, in Downloads, or anywhere — no need to move it.

If you open that folder, you may see a file named manifest.json. That is only a check that you unzipped correctly. In Chrome you will not click that file — you will select the whole folder later.

Tip: Remember where the video-downloadr-extension folder is. Next you load that entire folder into Chrome (not the zip, and not a single file inside).

Open Chrome’s Extensions page

In Chrome, click the address bar at the top (where websites are typed), delete what’s there, type exactly this, then press Enter:

chrome://extensions

Or: click the three-dot menu (⋮) → Extensions → Manage extensions.

Turn on Developer mode

On the Extensions page, look in the top-right corner for a switch labeled Developer mode.

Click it so it is ON (usually blue/colored when on).

New buttons will appear, including Load unpacked.

Load the plugin (select the whole folder)

Click Load unpacked.

A file window opens. Browse to where you unzipped the download (Desktop, Downloads, etc.).

Important: Select the folder named video-downloadr-extension itself — the entire folder — then click Select Folder (Windows) or Open (Mac).

✅ Correct: highlight/select the folder video-downloadr-extension
❌ Not the zip file video-downloadr-extension.zip
❌ Not a file inside the folder (do not open the folder and pick manifest.json in Chrome)

Chrome’s button says “Select Folder” for a reason — you are choosing a folder, not a single file. If you double-click into the folder and only see files, go back up one level and select the folder.

When it works, Chrome lists Video-DownloaDR.com on your Extensions page (not any other name).

Pin it (optional but helpful)

Click the puzzle-piece icon in Chrome’s toolbar → find Video-DownloaDR.com → click the pin so it stays visible.

Reload YouTube, then use it

Go to youtube.com and sign in if needed
Reload the YouTube page (refresh / press F5 or Cmd+R) so the gold ↓ MP4 button can appear — if a video tab was already open before install, it needs a refresh
Open any video so it plays
Under the video (near Like / Share), click the gold ↓ MP4 button
Leave quality on Best (or pick another) → Download MP4
Wait for “Processing…” then save the file when your browser asks

Don’t see ↓ MP4? Fully reload the YouTube tab after installing. Then open a normal watch page (a single video playing), not only the YouTube home feed.

Microsoft Edge

Almost identical to Chrome. Same zip file.

Download and unzip

Download video-downloadr-extension.zip, then extract it so you have a video-downloadr-extension folder with manifest.json inside (same as Chrome steps 1–2 above).

Open Edge Extensions

In the address bar type:

edge://extensions

Press Enter.

Developer mode → Load unpacked

Turn Developer mode ON (left sidebar or top of the page, depending on your Edge version).

Click Load unpacked → select the entire video-downloadr-extension folder (not a file inside it) → Open / Select Folder.

Reload YouTube, then use it

Open or refresh a YouTube video page (reload after install so the button appears) → click gold ↓ MP4 under the player → Download.

Mozilla Firefox (desktop)

Works on desktop Firefox. Temporary install (you may need to load it again after restarting Firefox).

Download and unzip

Download video-downloadr-extension.zip and extract the video-downloadr-extension folder (same as Chrome).

Open Firefox debugging page

In the address bar type exactly:

about:debugging#/runtime/this-firefox

Press Enter.

Load Temporary Add-on

Click Load Temporary Add-on…

Firefox is different from Chrome: here you open the video-downloadr-extension folder and select the single file named manifest.json (not the zip).

Click Open. You should see Video-DownloaDR.com listed.

Note: Temporary add-ons are removed when you fully quit Firefox. Load it again the same way after a restart, or keep the folder handy.

Reload YouTube, then use it

Refresh YouTube after install → open a video → click ↓ MP4 → Download.

Still stuck? Chrome/Edge: select the whole video-downloadr-extension folder (not a file inside). Developer mode must be ON. After install, reload your YouTube tab so the gold ↓ MP4 button appears. Look for the name Video-DownloaDR.com in your extensions list. Safari is not supported.
