Does what it should. Five stars. :-)

@Joe Herbert: Thank you! It is really good now.

EDIT: the comment below has been mad obsolete, please ignore.

The huge bold font is brutal on the eyes and makes one turn away from SL. One star off. Please make the font small and unobtrusive, or, better, to be set by user, for different screen resolutions and user tastes. EDIT: fixed

For narrower sidebars, the DL name breaks into only two lines, which is far too few. One star off. Please allow up to, say, ten lines, for cases with few downloads but a need for maximum page width. EDIT: fixed

@nope: have a look at Download Statusbar.

A more than worthy successor to the old "Downloads sidebar" addon that is not listed here any more.

The only nitpicks from my side: the entries in the list are rather large (both font and the fact that every part of each entry (time, size, mime type if active) takes its own line, regardless how wide the side bar is - mabe add an information area to the bottom that shows this information as the Vivaldi Downloads sidebar does?). Zooming with Ctrl+mouse wheel to make them smaller works, but the setting is not persistent.
