Great, so I fix one problem, only to be confronted with a shiny brand NEW problem. Version 141.0 Fixed the "T-bird lockup" when composing emails, so that's no longer an issue - - YAY. Now, Tbird refuses to save drafts. I had it set to every minute while I was having issues with lockups; now, I'm seeing a "can't save draft' popup every minute. I mean really... I haven't changed ONE thing in the machine other than changing that "0" to a "1" in "about:settings." Is there something about that particular fix that could cause this "save no drafts" issue? Don't have a clue where to even begin, since it cites either network issues OR file-access issues, and I fail to see why either would suddenly be an issue where it wasn't prior to fixing the lockups. Anyone have any pointers where to start looking? I keep seeing reference to Tbird "logs," but have no idea where to find those. Seems a reasonable place to start (after all, it's the first thing I look at when my 3D printer goes nuts!)
