Hey, on the addons website there a file for Debian Linux or tar.gz file.
How do I install it?

I have to admit I have no idea what vdhcoapp or DownloadHelper is (please elaborate) but this all sounds like you could use
youtube-dl
(which is in Fedora’s repositories)

This is an extention that enable you to download videos that are streaming.
https://www.downloadhelper.net/
what is this?
OK this is nice!
Edit: I tried but this didn’t work for me (university website not youtube)
This is the website to download the software I need to install.
It says “based on youtube-dl”, why not use youtube-dl directly.
The name of youtube-dl is confusing, I agree, but the software works with almost any media streaming platform, not just youtube…
just give it a try:
youtube-dl URL
I got this Error
ERROR: Unsupported URL: https://sso.apps.openu.ac.il/login?T_PLACE=https://opal.openu.ac.il/auth/ouilsso/redirect2.php?urltogo=https://opal.openu.ac.il/mod/ouilvideocollection/view.php?id=5695491
looks like they don’t want me to download the lecture, even if it is for private use 
(no reliable internet connection at work)

That seems to be an authentication error. The video is not public, and when accessing it redirects you to a Single-Sign-On page (sso.apps.openu…). Not sure how to deal with it using youtube-dl. In that case the FF extension would be easier…
I guess you have to figure out how to compile the source for Fedora. The authors don’t provide rpm package, nor building instructions: GitHub - mi-g/vdhcoapp: Companion application for Video DownloadHelper browser add-on
If you fiddle around, you may be able to use youtube-dl using your browers cookies (after logging in): https://www.google.com/search?client=firefox-b-d&q=youtube-dl+authentication
OK, I will try that, Thank you!
1.- Downloadhelper is an add-on for firefox you can download here:
https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/
2.- To install vdhcoapp is a Companion Application, you have to install from source tar.gz:
Some operations required by Video DownloadHelper cannot be performed from within the browser. In order to be able to still do the job, the add-on relies on an external application that is called transparently. We call it the Companion Application .
a. Download form → here
b. and check → Extra step required to complete install

Thank you for your answer,
So I opened the terminal in the file directory, where the file is located and did
$ install net.downloadhelper.coapp-linux-64 -t /home/me/install
*install is a directory I created, the install command required a destination.
The above command " install --user" returns “command not found”
cant tell if it actually did anything
1.- you’ve had to execute this step in order.,
2.- did you extrat it first…?
3.- First extract, this expand the Directory in your home…
tar xf net.downloadhelper.coapp-1.5.0-1_amd64.tar.gz -C ~
4.- Then, execute from your home:
~/net.downloadhelper.coapp-1.5.0/bin/net.downloadhelper.coapp-linux-64 install --user
Output
VdhCoApp: VdhCoApp is ready to be used
5.- Open Downloaderhelper, click on preferences and expand Auxiliar Aplication installed:
Found Aplication Auxiliar AplicaTiĂłn: *VdhCoApp 1.5.0*
Root Aplication: */usr/local/net.downloadhelper.coapp-1.5.0/bin/net.downloadhelper.coapp-linux-64*
6.- It doesn’t find click on → re-check
