Have used it for years, always worked faultlessly, downloaded very efficiently, never had any problems. But now - new version has ruined it. Before you could see and select the different possible downloads wherever you were without leaving the tab. Now it opens in a new tab which completely interrupts everything. A bit like having to stop your car and get out just to put on the indicator. Yes, it's that irritating. Also the downloads would show up in the Firefox download tab, you could monitor progress and see all ongoing, finished or failed downloads that way, very simple, very clear and again with no effect on the current tab. Now nothing there. To continue the car analogy, the dashboard has just been taken away, no speedo, no rev counter or fuel gauge. Feels like a spectacular own goal to me, but it seems to be deliberate. And where do you set the download folder, don't tell me you can't set that any more, but it certainly isn't obvious if you can.

Helpful response from the developer explains that it has had to change because of Firefox so beyond their control. Therefore up-rated to 4* as I guess it is still the best of the available options and hopefully they will find ways to get it back to earlier functionality.
