Firefox 57.0.1 is a fiasco. The latest rendition of Firefox has broken a lot of the features that made Firefox my browser of choice, like the ability to use extensions that actually WORKED and worked efficiently, like Down Them All (DTA). Compared to that extension, Bulk Media Downloader is a letdown--a mere shadow of what it should be. I have found that the same is true of most of the replacement extensions that work on Firefox 57+. DTA just worked, and it worked very well, without having to have a "grabber window" open to add media.

All "bulk media downloaders" should follow the lead of DTA.

Firefox has taken away all the browser features that we enjoyed and forced upon us a cheap, inferior substitute that doesn't allow the very extensions that make Firefox the best available browser. As with the new "replacement" extensions, Firefox is a shadow of its former self. The only viable option that I see is to uninstall Firefox 57.0.1 and reinstall an earlier version that does allow DTA and other favorite and helpful extensions. So much for Mozilla's looking out for the privacy and security of its Firefox users, and for its stated commitment to giving Firefox users the best browsing experience.

I agree with "pippo_franco"; "If it ain't broke don't fix it." That seems to be exactly what Mozilla has done with Firefox and the extensions that it allows.
