6.42 build 62 not working at all with firefox portable 148.0
At least on youtube. It's not even showing the download button. No matter how many times i reinstall.

When i used it, it whined about "missing config files" and when i used my laptop a few days later,it lagged it sooooo hard. worst extention ever!

Even with allowing: "Show download panel for protected content which IDM may not download" it stopped working from one day to the other. Reverting to previous versions 6.41 or other older builds and so on will not fix it either.... Fix it.

Can't download certain videos.

Initially, this thing didn't do what I wanted it to do. So I uninstalled it. It forced my computer to restart and logged me out of literally everything I was logged in to. Feels like Malware at this point. Do not download.

Every time I open the YouTube website, this IDM extension causes the main program to launch automatically, forcing me to manually close it. It's really annoying!

Everytime I open youtube the desktop app starts by itself and it's annoying.

The module of both this and chrome messing-up with naming rules of all other image downloader extensions I installed and I have to turn it off to fix it.
Consider to make it right on next version release.

Doesn't work on youtube.

Stop deleting my reviews. The latest update DID NOT fix the download panel issue. Most of the time the panel doesn't pop up and when it does, it only offers 360P as a download ... please re-investigate. :( UPDATE: V6.42.50 did NOT fix the problem ... still no pop-up) (V6.52 still nothing - WTF ... can we please revert to a working version like 6.30 ... geesh people!!!) Just updated to 6.42.58 on 18Dec2025 and now the download panel on YT is gone again, FFS people !!!

I bought a piece of junk software for $50 and can't download YouTube.

You've ruined this add-on mozilla! You can't choose the download quality anymore on youtube.
You've shut down the other working add-on to this.
Such a disappointment to a great pc app

This does not work on youtube anymore

still no option of 1080 pixel download ytb on mozilla,only 360p available with idm,chrome not working at all

Youtube don't work anymore, dwld button is not being displayed

IDM is not working on youtube while using Firefox, I believe that it is time to switch to other browsers
