имеется проблема с аддоном. Он ломает встроенный механизм закачки firefox. При попытке сохранить файл в конкретную папку - он всегда сохраняется в папку загрузок по умолчанию. В настройках указано "игнорировать закачки меньше 50 мегабайт". и отключено "передавать папку сохранения". Раньше с такими настройками всё работало корректно, сейчас оно сломалось. Разработчики аддона проблему игнорируют.

Extension safety
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.
Download Master requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on
Firefox Browser Add-ons, the amount of time the Firefox add-on has been
around, and other signals about the
Firefox add-on. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Firefox add-on.
Download Master has earned a fairly good reputation and likely can be trusted.
