Once it used to be a great app. Now it's kinda crap. Uninstalling or resetting it helps only for a while. The moment I enter a site with loads of vids the app inflates RAM to 20GBs and more.
Devs, revert it to the state when it was faultless!

This app crashes firefox, have reverted back to a past version, have now installed latest version, won't detect videos while playing, still crashes firefox, used this for years with no problems, how can this be fixed?

There is no way I could give Ant video downloader less than a 5 star. Having used many downloaders I find this one to be the best at this time.

Ant cannot download videos..

EDIT:OK i think Ant is good again.. after a few updates..

ne marche pas pour mon site

Used to work. Then started keeping all history and slowing down the whole browser.
That got fixed but now I get a "encryption key mismatch" error message on everything....
Wish I could just find the old version that worked.

don't install!! kill my firefox, need reinstall

Unfortunately, once the best program for downloading videos has slipped into complete shit. The program does nothing but consume almost 100% RAM and freeze the browser (Firefox) and computer. Do not install

I use the AddOn since a long time.

Version 4.13 of the addon is working again, where version 4.12 was buggy and unusable !
Version 4.9 was the best up to now. I have made a reset to 4.9 for my computer, sorry ;-)

Please add four features to your addon 4.14:

1. show the number of still working downloads.

2. please enhance the clearness in the window "all-video-downloads".

3. Please process changes of the settings immediately and not only reentering the settings-window (uncommon)

4. please add a checksum (i.e.MD5-checksum) in the download-info, that we can check it after the download of the native client and anytime later.

Thank You

Generally it does the job , but i wonder why it never detects Facebook videos.

Hello, this add-on works perfectly, except that I want to download videos from a streaming platform, but every time I download a video it is downloaded in its lowest quality (for example if I select 720p, the downloaded one will be at 480p). How do I fix that? (sorry for mistakes, english is not my first language)

Since end 2021, use too much cpu/ram... making Firefox very slow and the app sometime unusable (at best, can download 1 video at same time, during this time, it not responding).

Uninstall/reinstall addon and native app is not better.
Wipe out an reset work, but only for some days.
Must reset every 2-3 days for have not too much problem.
It's like if all videos detected are never deleted of the memory of the addon, and continu to use ressources.

PS: Sorry for bad english level.

So, the latest reviews seem to say this doesn't work but it's working fine for me. There's a comment from the developer I saw on one of the bad reviews that says the person needed to reinstall, I'm guessing maybe an update borked the extension for some people, and I can say that seems to track considering my new install is fine. If that changes I'll update this while leaving this first impression so people get the whole story. (If that's possible, I've never bothered to review something on here so I don't know yet.)

like all the other reviews say, this extension USED TO BE the best. But at the end of 2021 they made it useless, now all it does is freeze up firefox and if you don't remove it fast enough it will freeze your entire computer. There are no fixes as of Jan 29, 2022. Uninstalling and reinstalling DOES NOT fix anything, uninstalling and reinstalling the native app will also DO NOTHING TO FIX IT, it will work for a day or two but then it will go right back to freezing everything. Uninstalling and reinstalling firefox will also not fix the issue. It's a real shame that they ruined this extension it worked great for years, but now it's completely worthless.

makes Browser unuseable. its like trying to run Windows 10 at a 386 dx 40

update: need every start about 4-5 minutes to reset the extension that firefox works and that with an amd 3950

блин. тупит не тормозит и ничего лишнего / Просто убожество вешающее мозиллу

After removing 4.12, installing 4.13 and resetting it is working pefectly for me again!

This extension used to be one of the best video downloader up until the end of 2021. Moving to the new interface and changing the native app code (the file size is 4 time bigger), it slows down FF so much that it cannot even load the drop down menu to show the detected videos.
I disable this extension for the moment until the developers decide to make it work again.

Update: I did reset (wipe out) the extension and I also contacted the developer with their support form. They answered that the extension is meant for more powerful computers (as if an i7, 8GB RAM is a low end computer?)

Latest update broke it. Latest version of firefox. Tried reinstalling with same result.
