You can download an FB video in a chrome browser with no plugins / other software required. (As long as you are logged into FB and have permission to view the video).

<ol>
<li>open up the video and r.click for Get Video URL (copy it) -if you have the option "Copy URL at current time", use that option instead of "Show video URL"</li>
<li>paste that address into another tab and replace the www with m e.g. <a href="https://m.facebook.com/MusicIsMagico/videos/2645908645633407/?t=0" rel="noreferrer">https://m.facebook.com/MusicIsMagico/videos/2645908645633407/?t=0</a> </li>
<li>play the video, while it's playing open the dev tools and go to the elements tab</li>
<li>search for mp4 till you find a source address that's inside the
video tags - which will be inside a div that also contains another address with forward slashes and .mp4 in it.
e.g. 
<a href="https://i.stack.imgur.com/R0zjg.png" rel="noreferrer"><img src="https://i.stack.imgur.com/R0zjg.png" alt="FB video URL"></a>

<li>copy this source address. When you copy the address, chrome (if that's what you are using) does the html replacement for the ampersand characters. You will need to put them back. So replace the "&amp; a m p ;" (&lt; had to space that so it doesn't get converted here) separators in the address with just &amp; - use notepad find and replace or something ) and paste in another tab. Drop any parts of the URL that have frame sizing etc.. so you address should look like this:</li>
</ol>

<ul>
<li>this will load
your browsers default html video player which has a download button

<ul>
<li>this will all only work if you are logged into FB and have permission to view the video (doesnt' work incognito)</li>
</ul></li>
</ul>

Getting the right URL can take a bit of playing around but it works when you've got it right

<ol>
<li>In Google Chrome, go to Facebook.
</li>
<li>Open the Chrome Developer Tools (F12).
</li>
<li>Go to the Network tab in the Developer Tools (it's at the top of the Developer Tools window) <img src="https://i.stack.imgur.com/84pqA.png" alt="Network tab" />
</li>
<li>Play the video you would like to download on Facebook. Let it play for a few seconds and look at the Network tab during that. Long strings of numbers will appear every couple of seconds. <img src="https://i.stack.imgur.com/GESCV.png" alt="" />
</li>
<li>Right click one of those strings, then go Copy&gt;Copy link address
<a href="https://i.stack.imgur.com/F3Pbi.png" rel="noreferrer"><img src="https://i.stack.imgur.com/F3Pbi.png" alt="enter image description here" /></a>
</li>
<li>Paste (CTRL+V) the link you copied somewhere (eg Notepad) and remove &quot;&amp;bytestart=3684046&amp;byteend=3862768&quot; from the end.
So I have a link like:
<blockquote>

&amp;bytestart=3684046&amp;byteend=3862768
</blockquote>
After you cut the bold part out, the link that points to the full .mp4 or .webm of the video is:
<blockquote>
https://scontent-waw1-1.xx.fbcdn.net/v/t66.18014-6/46772657_738781116188283_6399514850013601801_n.mp4?_nc_cat=107&amp;efg=4yJ7ZW5jb2RlX3RhZyI6ImRhc2hfb2VwX2hxMl9mcmFnXzJfdmlkZW8ifQ%3D%3D&amp;_nc_ht=scontent-waw1-xx&amp;oh=91a5abdd5608768a05fd884773a45802&amp;oe=5C29B042
</blockquote>
</li>
<li>Open the modified link, right click the video inside and select &quot;Save video as...&quot; <a href="https://i.stack.imgur.com/eIhWf.png" rel="noreferrer"><img src="https://i.stack.imgur.com/eIhWf.png" alt="Right click video to save-as" /></a>
</li>
</ol>
Sometimes, when you open the link you may get just the audio of the video instead of the video itself. 
That's because Facebook downloads the audio and video separately. Just try repeating steps 5-7 with a different string of numbers till you get it right. Instructions to reduce the chance of accidentally picking an audio link are below.
If you need to download many videos and don't want to guess whether your link points to audio or video, type <code>larger-than: 50k</code> (or more) in the Filter field in the Network tab. You can also click the XHR button in Filters so it doesn't show non-video files like FB images.

Another alternative that worked in Firefox in Feb 2021:
<ul>
<li>Open the post's permalink</li>
<li>Change the page's URL - replace <code>www</code> with <code>m</code> and load that</li>
<li>Now use Inspector to navigate down to the div containing the video object - and the video URL will be a direct link</li>
<li>Copy-paste that URL into your browser, or create an anchor link to that URL and load your link and right-click to save destination.</li>
</ul>
It downloads as mp4 including video and audio.
<h2>Update, 2 Jul 2021</h2>
When I followed my own steps today, pasting the mp4 URL returned a page giving the following error:
<blockquote>
Bad URL timestamp
</blockquote>
However, I still found a work-around.
Side note: One of the containing divs has ID <code>mobile_injected_video_feed_pagelet</code>.
Facebook now injects the video element when you hit the play button.
That <code>VIDEO</code> element contains the URL you need. The URL does contain &quot;MP4&quot; in the path.
What I did was:
<ul>
<li>Open Inspector</li>
<li>Hit &quot;Play&quot; on the video</li>
<li>While the video is playing, find the <code>VIDEO</code> element and copy the URL from the <code>VIDEO</code> element</li>
<li>Paste that into a new tab</li>
<li>The new tab would show a smaller thumbnail of the video</li>
<li>Right-click the thumbnail and save the media to your PC</li>
</ul>
You must hit play for the <code>VIDEO</code> element to appear in the page source.
I'm using Firefox but any browser with an inspector should work.

blocks|key|474959|text|我根据不同的答案组装了这里所需的步骤：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|474960|Facebook分别下载音频和视频，因此从google铬检查器获取音频链接，右击视频并选择检查，转到检查器，网络选项卡，并检查链接，使用筛选器:大于:+50k在过滤区域选择更大的文件(根据视频的长度更改50k)，查看mp4或wav链接的结果，从链接的末尾删除&bytestart=number_here+&byteend+=number_here，打开它并下载音频。|ordered-list-item|style|BOLD|474961|从google检查器获取视频链接，使用上面的相同步骤，打开链接并下载视频。|474962|现在，为了混合音频和视频，我们需要使用ffmeg：|474963|从您的操作系统的网站下载ffmpeg构建，使用以下链接|474964|解压缩下载的zip文件|474965|打开命令行工具和cd到：\Downloads\ffmpeg-2021-04-28-git-1ab74bc193-full_build\ffmpeg-2021-04-28-git-1ab74bc193-full_build\bin+(根据下载的版本更改)|474966|假设输入文件位于当前文件夹中，则输出也将在当前文件夹中生成。

I assemble <a href="https://www.techandlifetips.com/tutorials/download-video-from-facebook-comment" rel="nofollow noreferrer">here</a> the necessary steps from the different answers :
<ol>
<li>Facebook downloads the audio and the video separately, so get the
audio link from the google chrome inspector, by right click on the
video and choosing inspect ,going to Inspector, Network Tab, and
checking the links, use filter:larger-than:50k in the filter area to
select bigger files (change 50k according to the length of your
video), look in the results for mp4 or wav links, remove
&amp;bytestart=number_here &amp;byteend =number_here from the end of the
link, open it and download the audio
</li>
<li>Get the video link from the google chrome inspector, using same
steps above, open the link and download the video
</li>
</ol>
Now in order to mix the audio and the video, we need to use ffmeg :
<ol start="3">
<li>Download ffmpeg build for your OS from its website, use this link
</li>
<li>Extract the downloaded zip file
</li>
<li>Open your command line tool and cd to :
\Downloads\ffmpeg-2021-04-28-git-1ab74bc193-full_build\ffmpeg-2021-04-28-git-1ab74bc193-full_build\bin
(change according to which version you downloaded)
</li>
<li>Assume the input files are in the current folder, the output will be
generated in the current folder too
Mix the audio and the video with ffmpeg using command : 
.\ffmpeg.exe -i video.ext -i audio.ext -c:v copy -c:a aac output.mp4
</li>
</ol>

I found <code>blob:https://www.facebook.com/c7e5a634-2343-4464-a03e-4a1987301ca1</code> video source on Facebook's private group and I really can't download the video by entering the url nor am I able to decode. Is there any way to decode this?
