Download managers/mass downloaders have been similarly rendered impotent (can't download to outside of the Downloads folders without individually prompting for each and every download [1], can't intelligently handle naming conflicts between new downloads and existing files [2], etc. etc.)
And somewhat ironically, while I already had it installed for quite a while, I only really started seriously using and valuing DownThemAll after Firefox 57 had already come out.
[1] Eventually they relented somewhat and said that they would accept an API extension whereby an extension could download to the last downloaded-to location (even outside of the Downloads folder) without having to explicitly prompt the user again – but until now it was never actually implemented (https://bugzilla.mozilla.org/show_bug.cgi?id=1342563).
[2] You can only choose between "automatically rename" or "overwrite", and you can only choose in advance (!) when you don't actually have the necessary information to make that decision (especially seeing as Webextensions can't read any local files, so they have absolutely no idea what sort of filename conflicts could potentially exist). There's no "skip" option, and while there's a "prompt" option (however well/badly implemented that might be), Firefox doesn't even support it.
