Don't go download Torch internet browser link, based off Google Chrome, with the built in torrent downloader
And don't go to this link and click on the little magnet, then choose where you want to download to
Remember, if anyone asks, "you can think about it.. But don't do it"
Oh also don't download Ublock origin to prevent pop ups, and don't stay safe by trusting uploaders/files with green and purple verification's, to prevent viruses
There are many ways. On Windows, the laziest thing is probably to use a browser with a built-in downloader. Like this one or find some extension to your Chrome/Firefox.
Or paste the Reddit URL into some dedicated downloader application. Like JDownloader.
For those who are not afraid of command-lines, youtube-dl also works with reddit. You need to open a command-prompt. Take note which directory it starts at (if it says C:\Users\Raider\_Rash> then that's your home directory and where the video will end up). The command youtube-dl <url> will find the video and download it.
For example, to get this video, copy https://www.reddit.com/r/PoliticalHumor/comments/aeduyp/if_there_is_a_concrete_wall_in_front_of_you/ from the address. Go to cmd. Type
youtube-dl
and right-click and paste.
(Why did I not copy the full URL? Because there is an "&" so you would need quotation marks ... but you don't need that.)
