For string prefs one should be able to specifiy a min/max string length (or at least max length). Also it may be possible to make the input size proportional to the max length.

Does this include implementing textareas / multiline inputs, or should I create a new bug for it? Comma-separated lists of words begin to be unreadable very quickly in those simple one-line inputs.

Huh. I don't really think that having a separate "list" preference type is worth the pain (because textarea is enough IMO), but once you asked, I mocked a quick example (based on Stack Overflow tag list, it was the first similar thing that caught my eye): http://i.imgur.com/2DGts.jpg Would it be a reasonable feature with fair usage (read as "Should I create a bug for it?"), or is it too much?

currently the expected way to do this would be in options_xul.py, but since python code is going away (hopefully) soon, maybe this isn't a "good first bug", and also maybe it should be re-triaged..
