Just want to report that doing a full "Wipe Out And Reset" under "Settings" completely solved the memory leak/build-up issue! Some weird UI issues (affecting other Firefox addons as well) also disappeared after the reset.

(Hopefully more Firefox users are able to figure this out, or they might think it's an issue with a Firefox update & switch browsers... >.<)

I wish to confirm you that uninstalling and then re-installing AVD following the procedure you described for resetting the cache has solved the memory leaks problem.
Keep up your good job !

Currently (1/7/22), Ant takes up more than 5Gb of memory rendering Firefox unusable.

be very careful with this, there's a huge memory leak, I was at 20,000mb yes 20gb in my firefox browser in the last week or so, 01-06-2022 and I thought something was wrong with my net connection, updating games or devices, nothing, and I turned off about 25 addons in firefox, it was the ant. it took over 5-6gb just in the main window with nothing in it waiting to browse with some text boxes of other interesting news ff plops on there for $. when the meory leak is fixed, I'll put this back to 5/5.

It worked great until today. Now it eats all the RAM it can get and a lot of CPU immediately after browser startup. Currently, the addon makes using the browser impossible, so I had to disable it.

UPDATE:

After deleting the addon and adding it again, the addon seems to work great. No memory leaks at all.
I am updating my score to 5 stars

ORIGINAL:

It was working great some weeks ago. Now it's impossible to work with it.

Has huge memory leaks when I open it. Firefox ends taking all of my RAM (12 GB of my 16GB). My computer gets laggy and I have to close Firefox just 5 minutes after opening it.

I will disable the addon until this big issue gets fixed.

It was a great addon, but not anymore.

EDIT:


Many thanks dev team, the reset solution solve the memory leak issue.
Back to 5 stars !

I had to retry several times because even getting the settings tab clicking on the icon was imposssible due to memory leak bug triggering immediately after start.

So you're probably right the extension storage was corrupted after upgrade and caused this bug.

Why not releasing a new version which auto-resets at first start after installation in order to solve the issue for everyone ?

I used this shortcut to get into the settings without the annoying button bug (UUID should be different, identify with Firefox "about:performance" tab):

moz-extension://b3f1c4cd-c575-44b6-b256-5524cf739da3/ui/frontend/dist/settings.html

Then, first reset try hanged (memory leak again).
Next time I uninstalled extension/ restart Firefox / reinstalled the extension and used the reset option again which at last succceeded

thank you for posting this solution !

This Addon used to be so great so this pains me to write this review.

The new update after V4.8 messed everything up on my PC. This update made my browser so slow and laggy that I thought I had malware on my computer. I even uninstalled and reinstalled my browser and performed a system restore which all turned out to be unnecessary because the culprit of my problems was right under my nose all along and I didn't even know it.

Once I disabled the Ant Downloader performance on my browser all returned to normal with no more lagging. I hate to say it but this is a BAD extension now and I don't intend to use it anymore unless their are same massive changes in the works to get this extension back on track.

Do better AVD!

It has become awesome again, thanks!

Minor issues:
- Please add a horizontal scroll in all downloads page. Tablet view, cuts half of it.
- Reset failed downloads disappear and don't appear anywhere.

UPDATE 2-16-2022
It's broken again. Please fix!

Does exactly what it's supposed to do. A clean install fixed the memory leak issue.

*SOLVED*

Used to be amazing, but now has a serious bug that maxes out your CPU and RAM usage. Be careful with this one.

This add-on is still the best at what it does. When Down-Them-All failed, it's the only thing that's worked.

Please, next time, don't release a new rebuild of your work before major holidays. Wait, test it some more, then drop it when you can fix it.

Love the work, thanks for the fix! Updated 1/8/22

I'm not sure what happened to my go-to video downloader after this "update". It shows every type of media for download in a cluttered UI and the list of issues goes on and on.

Δούλευε μια χαρά, ώσπου πρόσφατα σταμάτησε να δουλεύει και προτρέπει να κατεβάσω ένα πρόγραμμα - όχι πρόσθετο αλλά εξωτερικό - και να το τρέξω.

Up until a few days ago before it was updated, this was the go-to downloader fo me. Now it takes forever (up to 5-10 minutes for the videos to be detected) and there is no button to clear the cache. It still lists downloads on sites from several week ago which totally clutters the video list. I've had to remove the add-on and reload it to try to clear this annoying cache memory.

2021-01-03 This "NEW" version is AWFUL!!! Bring back the prior one which actually worked and was VERY USER FRIENDLY, unlike this garbage!!!!

it used to be a great app - since last update - uberjunk - uninstalling it... it is soooo slow now, UI is messy, you can only see a small white line and the whole browser is dead slow, worst update in software history, they took an amazing plugin and turned it into an unusable service. bravo.

one of the best video downloader ever, grat job guys keep going

What once was great with release 4.9, is now 100% junk with version 4.10. Instead of just listing vids, downloading/downloaded it now logs every vid that runs on any web or social media site. There are better, easier, to use, down-loaders for YouTube, Twitter, Facebook ect..., than Ant. Just wait until you try to delete or clear the Ant list. What fun that is. IMO, ANT is nothing more than another form of spy/tracking ware. I have dumped it and will not go back to it after reloading version 4.9. that now runs with the newer junk as well.

Recent end of 2021 updates - super slow, messy User interface, lag, not showing display well, tabs not displaying, slowing down everything. gosh. so bad. uninstalling. It used to be fine, simple, efficient, bbut what the hell are with the recent updates. If its not bbroken, dont change it.

I totally agree with some of the comments posted by other users :

Worst update ever...
There is not just 1 problem, there are many.
The popup to start the download only appears as a small white line, downloads simply stall, the list of videos grows and grows and cannot be reduced in size.

It used to be great, but now it is a mess...

Please, in the next update, go back to a simplified and user-friendly version !
