Works great for YT, PH, among other sites.
Note: users who are still using 32-bit Windows and who want to use the "native app", you will need to replace ffmpeg.exe and ffprobe.exe with 32-bit versions (google for download sites)

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..

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.)

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

About my previous reviews....
"AVOID 4.12

This was a great add-on until they tried to make it better."

I feel I was extremely unfair leaving such a harsh review.

You made something that a lot of people found useful, that includes me. It saved me hours of memory buffering waiting for videos to load and play. So, please accept my apologies I'm sorry.

All the complaining really resulted from your success with the addon.

Must have been somewhat gratifying and ego stroking to know people missed something you created. Unfortunately, some, well me, were completely ungrateful in the first place for it's existence, not to mention it was made available for free.

I really should have thanked you for giving the world this pretty cool and incredibly helpful addon.

So.. Thank you.

Thank you for your hard work, your generosity and your patience.

I hope the kinks get worked out and I promise to do better.

Ant Video Downloader es sencillamente excelente. Rápido, eficaz y confiable. ¡Gracias!

Buggy but, fast and functional.

Если вы ищите какое дополнение убило ваш браузер, вы угадали. Сейчас попробую полностью переустановить дополнение + программу, и надеюсь, что это исправит ошибку, и вам советую.

А дополнение само по себе классное, если этих проблем не будет, то оно суперское! Надеюсь, разработчики постараются исправить эту проблему, ведь сейчас у многих людей не работает браузер, и не все могут додуматься об отключении дополнений. Что уж там, даже мне пришлось потратить немало времени, чтобы найти дополнение, которое вызвало эти проблемы (У меня больше десятка дополнений). А Дети? Дедушки и бабушки? Они же не смогут всё это сделать...

Я очень благодарен разработчикам за дополнение, потому не стал ставить низкую оценку. Надеюсь, таких проблем в дальнейшем не будет.

Had any problems with overloaded RAM etc. De- and Reinstall did solve the problem.
I can say: MVP under the Videodownloader !!!!!

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... >.<)

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 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
