Well I finally upgraded to the latest version of Firefox only to find Ant Video Downloader is no longer a Video downloader at all. It tells you to install a companion App, the last thing I want is more bloatware, more stuff to go wrong, be scaned by virus checker etc etc. What a shame, this as RUINED and video downloader which pretends that you have a choice saying the companion app can do not, but the stupid Ant extension is not capable of even downloading a yourtube video. I wish you could just be more honest and stop wasting users time.
Please note that companion application is only used for merging streaming type video segments with help of included open source FFmpeg converter and have digital signature to provide secure. You can check it by any anti malware soft in case of suspicions.
Downloads work and whatnot, but if you leave it on, it will pile up processes and make firefox slow until my computer crashes. Seems like every single video it detects opens a new thing that consumes memory, eventually opening up hundreds of instances.
