Tried 2.8.0 - 2.8.7. None of them work consistently.
-----------------------------------------
The new version works for a day, then fails to detect any link. Reinstalling the addon and restaing Firefox make it work again, but only briefly. And I have to set up the customized command each time. I also need to ask it to detect direct links, or nothing shows up.
Also, when it is working, it detects way too many clips. The new clips are added to the top one by one, so the m3u8 link keeps moving down and is difficult to click. I suggest to add newly found links to the bottom. It also seems to ignore the "This tab"/"All tabs" settings and shows all.

When it worked, it was absolutely fantastic! I use it together with ffmpeg, but with user-command.

Works as advertised. Easy to use. I was able to catch radio stream from a web page and add it to my phone radio stream player just as I wanted.

a great add-on that provide a ready-to-use command for various CML applications, including youtube-dl and ffmpeg

this is exactly what i wanted for my streamlinks. holy $h1t

This used to work real well but from the past few updates getting more buggy. Not always copying into the clipboard the mpd links when I click on.

Best tool to use with youtube-dl!

Works great, not functional for all sites or streams but using it certainly lowers the burden on streaming. I can finally download some of the stuff I want for offline.

Excellent program. :) I use it on Windows 10 and it helped me a lot of times to download content i wasn't able to download using other methods. I would like to make a donation to the developer but don't know how to do it since I can not find such a button.
