This has been my go-to video download add-on for a couple of years, at least. Very prompt to adapt to Firefox updates as necessary, and the developer offers clear and concise directions and explanations for any changes or fixes that may alter the UI. Keeps you within the browser and seamlessly sends your download to your chosen destination folder. It has more features than I have had a need for, so far. I just can't complain! Thanks, mig!
