In regards to browser.download.lastDir.savePerSite It feels like this should NOT be a true / false option, but rather offer 3 options: 1) Do NOT remember 2) Remember Site/Domain (top level) 3) Remember specific server/subdomain Firefox currently offers only 1 (false) or 3 (true), which is absolutely INSANELY annoying on sites that are powered by dozens or 100's of unique servers who's URLs are not masked. When browser.download.lastDir.savePerSite=true, downloading a group of 10 files or images may require changing re-navigating your directory structure up to 10 times, which is just as bad / annoying as if it was set to false. Alternately, just remembering the top level domain instead of the subdomain or server would be MUCH better in every case I've so far encountered. Please consider changing this... !!!!
