Cant launch anything from status bar

I just lowered my review from 4 stars to ONE STAR because this add-on no longer works in Mac Catalina Public Beta 6. The developer is non-responsive. The add-on continues to work properly in Google Chrome.

I would give it 5 stars except for one very necessary but missing feature.

I cannot restart or resume a timed out or failed download. Imagine a 800 MB file 97% complete, stalled. Sorry, the hour spent downloading the 97% is gone, wasted, and I get to start all over again from 0%.

Other than that, it is a very good add-on and one I use all the timer.

The extension don't save download history. Useless for me. I'll change my review when the extension could save my download history.

I am using this addon on Firefox pre-57 and I am disturbed by one lack of option, in fact I use this addon for everything except the add-on taskbar. So I would like to have the button in the bar, except when I click on it it will open all the downloads in a new tab (while actually it will show a sort of pop-up that resumes the download, a sort of vertical pop-up).

So the question is how to enable the option to open the downloads in a new tab instead of a pop-up when clicking on the Download Manager button in the taskbar ??? Thank you
