I had this I think is the same one it worked great but then I googled out & lost it !

Unclear how this is supposed to work. I expect it to automatically take over any download, but Firefox still uses the default method. Also, is this actually a download accelerator?

I know the dev is responsive so hope he/she can help me get this to work as expected. Thanks.

EDIT:
RIP Oleksandr, you and your add-ons will be missed. :(

I hope the developer is ok. Just to let him know that Download Manager (S3) is breaking virustotal.com. For some reason the addon doesn't let me upload files to the site and the site triggers the captcha. After solving the captcha, the cycle repeat. Try to upload -> captcha->try to upload-captcha. Turning the addon off fixes the problem.

Queue is broken. You tell it to download 1 file at a time, then paste in 99 links, and it starts to download ALLLLLL of them. wtf?! It hits pause on every one as soon as it starts though, and randomly one will slip thru and start downloading completely. Often 2 are downloading at the same time. VERY broke feature. WTH can't it just actually QUEUE up what it downloads and just download 1 at a time? disappointed. lack of a lot of settings that would be super handy (like default download path).

how do you switch on queue mode

non-modern appearance and Checksum not work

Recently migrated from Chrome so this plugin seemed like a perfect solution to get Chrome-like download management, but after a few days I noticed Firefox' WebExtensions process was eating 7.5gb memory! Disabled this plugin and it's dropped to just 43mb. Clearly a memory leak in the code somewhere unfortunately.

Needs choice where to leave the download (temp. directory, default directory, etc). In particular, I want to get rid of downloaded, processed, Archives (rar, zip, etc) without taking further action.

I don't know why and how but it causes virustotal page bring captcha test infinitely

Unfortunately, there is no function to download links in a selected fragment of a web page or on the entire web page, with filtering by extensions. There is no way to save a link to the original location of the file in descript.ion. Or better yet, a description of the downloaded file added by the user.

Very useful except for one big flaw: no option to disable the confirmation window when you open a file. I clicked on it, yes I want to open it, you don't need to waste my time with a pop-up window.

我不喜欢每次下载出现的横条

Looks good but I was expecting this addon to preserve download modification timestamp :/

Era excelente, pero empezó a consumir muchos recursos, más en descargas múltiples (5 o más). A veces desaparecía la barra inferior y reaparecía de la nada. Se han producido varias actualizaciones, pero ninguna ha solucionado eso. La he deshabilitado hasta que vuelvan a lo que eran, sino la eliminaré

A good addon, but you're using a pre-existing Firefox Shortcut for one of your Addon Shortcuts.

CTRL+SHIFT+Z, which you have set to show and hide the download bar (a rather important function) is already the shortcut for Show/Hide Console in Firefox.

not launches a file by double-clicking in the associated program, not a photo not a text

1. Кб и Мб - это килобит и мегабит. Для байтов правильно КБ и МБ. А если уж совсем дотошно, то для 2^10 используется формат "киби" (КиБ И МиБ). 2. Когда закачка обрывается, в окне истории и в панели ctrl+shift+z пишет "файл не найден". После возобновления закачки (через родной менеджер ff) список обновляется, но в панели продолжает висеть потерянный файл.
