Does not do anything with Firefox 122.

Works great if only there is a auto clear option.

+ Feature that definitely should be implemented in standard version of Firefox. It's just stupid that Firefox forces user to do 4(!) clicks to get rid of downloads and also refuses to fix this obvious flaw.
- No option to also clear 'Show all downloads' list. Very sad.
- Violet icon color is too distracting. No option to change it.
- No option to edit ":) Cleared!" tooltip and remove annoying smile BEFORE text.

Did exactly what it is supposed to do

It doesn't clear my download list.
