firefox/iceweasel has worked just fine for years I just upgraded my home jessie machine to stretch. That went very smoothly, so far only one exception. I can no longer download anything with this browser. I've reinstalled, cleared out my profile, run in 'safe' mode (no add-ons such as no-script). I've tried other destinations, including "ask me" (it never asks). I only get the truncated error message: "could not be saved, because you cannot change the contents of that folder."
Turned off my firewall - no change. Tried downloading from other sources, no change. Epiphany downloads the same files with no problem. Has anyone else had this problem recently ? Looking at the Debian bug reports I saw a year-old report that looked kind of similar. Thanks for any insights! -Frank
