User Reviews

Being using this for years, extremely great plugin. However, recent "migrate to use download api to capture download" is broken! After I click download, it tries to save to a path by "X://aria2download/C://Users/Me/Downloads" which fails always! And right click link "Save As" will be captured to aria2 as well, which is not the behavior before 0.5.3.

Actually has an up-to-date version of AriaNG. This is the one you want.

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Aria2 Integration Extension requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
