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.
