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.

Recent updates have broken this extension, yes even the update as of 01-18-2022. The memory leak is still in effect as is the CPU use cycles. The only difference I can see is that the firefox.exe that is hammering the RAM will now close when closing the browser (before you had to kill it in the task manager.) This extension's high resource use is enough that I am considering it potential malware.

Update. After uninstalling and reinstalling the ap, the memory leak seems to be resolved, as is the CPU thrashing. The mod once again seems to be functional, I will increase the rating of this addon if it continues to work as designed for a few more days.

The latest update completely ruined this add-on. It absolutely destroys memory and performance for Firefox.

It makes the entire browser lag even when you're just opening a new tab. I confirmed Ant Video Downloader was the problem and haven't had an issue since disabling it.

Hoping for an update that makes it usable again but for now I don't recommend it.

Hey, loved your addon, but the 4.12 update ruined it and the 4.13 didn't fixed it. I'll change my review once it is fixed.

Someone created a complicated update and ruined the programming, now the extension is essentially a malware.

I had to uninstall the extension two days ago. I studied computer science and did some programming many years ago hence I still recognize a blatant MEMORY LEAK and THRASHING - meaning this extension exponentially consumes excess system RAM until virtual memory is activated essentially hanging your computer that even a proper shutdown is near-impossible. The memory consumption is uncontrollable and very risky for a hard drive. It took me quite sometime to isolate the problem to this extension. Once Firefox is activated the system RAM begins to run wild after about a minute.

The affected firefox process is the one controlling all firefox extentions, hence terminating it stabilizes firefox and the computer but it kills all active extensions. You can activate each extension individually, but the moment you activate this Ant Video Downloader the issue will begin again.

I wonder if software development standards have dropped so bad that a program like this is allowed on a major web browser like firefox, even though I have reported the problem no one seems to care. You guys should deactivate the extension until the issue is fixed, or just totally remove the last update and create a completely new update rather than try to isolate one issue in a bad program.

Recently, the ANT Video Downloader has ceased to operate. Thew icon is present, but it does nothing.
I've tried to update it, but that doesn't seem to work.

It worked fine until the last update. Now, this thing slows Firefox down to a crawl, eats >95% of my available RAM, and it is impossible to access the menu even after reinstalling it or restarting Firefox, before memory usage blasts through the roof, because the menu won't even show up.

Clearly, as many other users have said, the devs should revert to the previous version and leave it at that, because it was nice, unobtrusive and did the job as asked. We don't need no fancy stuff or whatever, just tell me what videos are on the current tab (limit the displayed list to 5 or 10 items if there's a lot of videos, with a link to open a complete list if needed, which should hardly ever be needed), allow me to select which ones I want to download and where, and that's it.

I'll keep an eye here to see if the devs come back to their senses, but I'm also going to look for other apps doing the same job. If I find a good one, I'm probably not coming back though. Too bad, this extensions had been awesome for many years, but not anymore.

Used this for at least a couple years, never had a problem. Uninstalled now because it's completely broken.

I'm not a techie, so I wasn't able to determine the cause of my recent PC problems and inability to get web pages to download prior to reading about the similar experiences of many others here with the ANT extension. The only thing my internet provider could suggest was a faulty modem since everything else checked out fine, so I unnecessarily spent over $100 to buy one, and endured the worst week of my internet surfing life, bar none. To the developers: you are clearly not following proper program development protocols to safeguard those who put their trust in you. It's time to start.

You guys have ruined the add-on since the last update. I see a list of 94 videos in the window. Whats wrong with you guys!!!! Why would someone be in one tab, and want to download videos in other tabs?

You conveniently steal our data, ask us to install that native app to steal all of our info, and then you guys make a shitty add-on which shows videos from all tabs?

Absolute shame

This add on sucks big time!!! Don't install it!! It will slow down your firefox and cause your hard drive to run like crazy which will eventually cause it to wear down and quit resulting in you loosing all of your files. I've reported these Fucking Bastards to Mozilla I don't know how many times and they refuse to do anything to them. So I'm writing up this review. These Fucking Bastards owe me $120 for having to replace my hard drive, not to mention lost data.

This is a classic case of if it's not broke don't fix it.

Now the extension is full of bugs and worse of all it has memory leaks which you can't reproduce and fix.

The last thing you want attached to your extension is memory leaks. You could seriously damage someone's computer with memory leaks which is not what anyone signed up for just to beta test your new updates with this extension.

Well I hope it was worth it AVD. You messed up a good thing and a bunch of people are going to uninstall this extension because of it.

Edit "Either please try to reset the data at the extension menu Settings - Reset, click the WIPE OUT AND RESET button"

Yeah that's basically like putting a Band-Aid on an open wound. The Memory leaks come back even after you reset and wipe out the data. I checked.

Uses too much memory and slows whole browser. Reinstalled add-on and native application, no help. Needs to be reverted until this mess is fixed.

I have one and only one question for you after performing your reset/wipeout fix for the memory flood problem which worked for a couple of hours then the problem recurred:

WHEN ARE YOU GOING TO REPOST THE PREVIOUS VERSION WHICH WORKED VERY WELL.

memory flood. Not usable 16gb of ram quickly full

4-5 GB of RAM usage, triggering virtual memory usage on disk too..!?? What happened?

目前版本（2022年1月7日V4.12）存在内存泄漏问题，千万别用，等更新看看再说，一个页面没有占用2G内存，随便开几个网页直接大鹏展翅翱翔于10G之上。搞得整个浏览器卡顿，所有扩展无法正常工作。
等更新完好使了再回来改评价

Recent update caused memory leak BAD...Dont tell me to update Native app..that is up to date. It is this extension via troubleshooting mode. Normal memory load is less than a gig. Enable this one extension and it skyrockets to 5GB immediately then crawls its way up to 8GB before browser is unusable and I need to kill the leaking process.

I found out this evening that this extension was causing Firefox to slow to a crawl. Thank goodness troubleshooting mode is there. I had to use that to finish removing this from the browser and made sure to report it for slowing down my computer.. You broke this extension with that terrible update. When it does load which is rarely. It loads every single video which can no longer be cleared. Your nonsense fixes are not worth the time based on the complaints i have read. Roll this useless update back completely since you can't get it to work properly and i will come back.

Whenever I install this plugin my computer slows down drastically. this cannot be normal.

AVD used to be Perfect! I could download it, use it, get the video file, and view it. It worked. Now, with every update it's getting worse and worse! Not only does it not work no more, my computer crashes so bad my only option is to hold down the power button and restart my computer. Why?! Why did you guys have to mess with perfection? It was perfect, it didn't need any updates! Now, your latest update needs to be updated again because not only does it not work, it causes my computer to crash!

Developer Response: Well sir what you need to do is...

No! What you need to do is re-upload "AVD-NativeApp-3.3.40-Release" Leave AMD alone and work on a different project. This gonna be like "Adobe Flash" just keep messing with it till you destroy it.

Causes memory leak on Firefox; it filled up my 16gb ram within a minute or two, the only way to fix it was to restart my computer.

"1) Start Firefox in safe mode (firefox.exe -safe-mode)
2) Remove AVD
3) Google "firefox remove extension data"
4) Remove extension data
5) Reinstall AVD 4.12. Wipe out storage for the final shot.

Get back if it didn't help."



Before reading your reply I've unistalled the extension and deleted most of the files that had antt in their content.

Reinstalled addon (and host app). Worked fine, so wipe/reset from addon options. Unfortunately after a few hours everething went back to the same shit with memory leaks.


Do you want me to remove all of the storage\permanent\chrome\idb contents? Like my other extensions data?


If the problem persists I'll prolly revert to the old version which I liked better (more streamlined, less clutter). Unless the problem lies with the host app.
