Until recently, whenever I downloaded a file, the Firefox dialogue requesting the destination folder started out at the folder I last used to download a file from that web site. Now it appears to always start in the last used folder, independent of web site. Since I seldom download more than one file at a time from a given web site, this means I have to navigate the directory tree for every download, which makes the whole process take two or three times as long as it used to. Is there any way to restore the old behavior? My searches on the web have only turned up suggestions that are accompanied by responses that say "That didn't work." (Running 101.0.1 on Ubuntu 18.04, if that matters.)

I know there are add-ons that will let me script the download folder selection process, and I'll go that route if I must, but I'm hoping that my preferred browser behavior is still available - "just works" is preferable to "you can beat it into submission if you try hard enough".
