by Firefox user 14276251, 6 years agoI've had this YouTube MP4 Add-on for several months and it has been working fine but after Firefox 62 came out it doesn't show up or appear to work. Hopefully this is some temporary thing.
Update 11/10/2018 - After Firefox 63.0.1 (64-bit) update this add-on doesn't work again. It is a great Add-on, hope it can/will be restored.
Update 3/19/2019 - After Firefox 66.0 (64-bit) update this add-on didn't work until I restarted my computer. It is a great add-on and I also bumped my review from 4 to 5 stars.
Update 5/3/2019 - As of this date now getting this message "YouTube MP4 Downloader could not be verified for use in Firefox and has been disabled." Hope not permanent as really like this add-on.
