Googling finally lead me to the setting "media.autoplay.enabled" in about:config. Changing that to false stopped the file from starting but still opened it in the browser window. I then looked through the other media.* config entries and found "". When I set that to false I now get the save dialogue box when clicking on the MP4 files.

Had been working, just quit Rated 3 out of 5 stars

As of 11/5/16 this add on, which had worked perfectly, just started opening the video in another screen without any downloading at all. Too bad.

Rated 2 out of 5 stars

Слишком мало вариантов качества видео

Fine Rated 3 out of 5 stars

This addon works, and have good minimalistic interface, but it can not download videos in quality more than 720p, so only 3 start for it

Perfect Rated 5 out of 5 stars

Honestly, couldn't ask anything more from this addon. I've been using it for a long time, it's nicely integrated to YT, works well and is updated quickly when there are changes to the way YT supplies its videos, I guess. Thank you for your work!

fantastic Rated 5 out of 5 stars

Excellent! Rated 5 out of 5 stars

Didn't work on Android firefox Rated 5 out of 5 stars

I visit mobile version of websites even on my PC via user-agent switcher, because its faster, safer, cleaner, easier, more adaptable to window size and updated more often. youtube's mobile version is among the best. but the download button doesn't appear there.

update: 5 stars

This user has a previous review of this add-on.

I'm not sure how you managed to install this extension in Firefox for Android, but it's not compatible. YouTube's mobile interface is completely different and it's not worth it to change the extension since you would still not be able to install it on Firefox for Android (at least not without editing the manifest file) because of the Google Play Store policies, which are enforced by Mozilla. No YouTube downloader in the Play Store, not even as a browser extension.

Simply works... Rated 5 out of 5 stars

...except not for 1080p and above. But 720 is OK too.

One of the most useful add-ons for Firefox. Very easy to set up, but also has many options. Highly recommended.
