Cannot handle Facebook videos. Likely can't do videos in segments.

I can't download Videos from Youtube. It gives the message, "Hmmm... No videos or Flash files here..." It downloads videos from Rumble just fine. Quick and easy.

Bug issue: When this add-on is enabled, I could not log in to overleaf. The overleaf website reports a bug: "reCAPTCHA placeholder element must be empty".
ryzen 4800h, Ubuntu 20.04.3 LTS x86_64, firefox 92.0 (64-bit), this add-on version 1.0.9.86 .

This add-on still works with Dailymotion, but not YouTube.

Isn't working for pornhub videos for me as of 02/28 - getting "no flash or video files here" or getting some AD videos

Isn't working for youtube videos for me as of 12/22 - getting "no flash or video files here".

Не позволяет скачивать видео в высоком качестве, не работает на многих сайтах.

Since I am rating it low, I will explain.

Sometimes it does not download the video.
For example the following does not work:
https://www.youtube.com/watch?v=LPxIssabhTc

Sometimes it downloads at 360p, although the video is playing at 1080.
Example:
https://www.youtube.com/watch?v=sIaT8Jl2zpI

As the following page states:

"The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords."

not that bad
