It's a great add-on. Speed improvement is remarakable, the resume capability is great and it also allows you to keep the "Browser Download" if you don't want to use it for a specific download.

The best Browser extension download manager. I like this!

为什么每次下载进度到达100%，还要等不短的一段时间，文件才真正下载完成？
自带下载进度100%就立刻文件完成了。

一直都很好用，但是最近在下载完调用内置下载时会报错：The operation failed for reasons unrelated to the file storage itself and not covered by any other error code.

不知为何腾讯微云不能同时下载两个任务，否则会有一个出错。

The operation failed for reasons unrelated to the file storage itself and not covered by any other error code.

最近在文件下载完成后出现了以下报错信息：
未知错误: The operation failed for reasons unrelated to the file storage itself and not covered by any other error code.
/background/multithreaded-task.js:569:21

Works great！Thanks

With the latest Firefox nighty 64bit, upon completion of download via Multithreaded Download Manager, I get the following error message.

this.mutableFile.getFile is not a function. Worked ok with previous Nightly Builds.

I am on Firebox 74.0a1 File version 74.0.0.7321

在Firefox 72上面不能自动接替内置的下载管理器了

Perhaps one of the best download managers for Firefox. But, is it possible to add the ability to choose where a temporary file is created? By default, Firefox writes a temporary file to the download directory, I would like the same behavior from this extension. A little stupid, but I do not like to create an extra load on the SSD.

It the best extension for download files. When you add minimise to tray :-) Will be 7*.
I uses RBTray (To minimise extension to tray). Can you add "ICO" to card manager. When I minimise your extension to TRAY, it haven't ICON :-)

it's great. but there is a little problem in it. the problem is: your extension is unable to complete the download because windows can't save a files that contains (:\|/?><"*) characters. is it possible for you to repair it in your new version? after a completed download, please automatically replace illegal windows xp characters with a legal character. for example: if the downloaded file was (test:test.jpg) after a completed download, automatically change it to (test-test.jpg) then automatically start the selected download again to complete the step two. using this way will save my time. because my downloaded files are more but after a completed download, i'll see this message for every downloaded file: (filename must not contain illegal characters) and i must click (edit) for every download and change the file name then click the play again :( thank you :)

this is the best Multithreaded Downloader I can find in Firefox for now, thank you.
tested under ArchLinux, works perfect
