While rebuilding Rosey's machine, I decided to see if I couldn't get Firefox and Thunderbird working on my machine. Problem I've been having is that there's nothing in the UI for the mail client (Thunderbird) for importing Mozilla 1.7 settings and messages (though there's lots for importing from other mail clients).

Anyway, it does appear that the only way to move from Mozilla to Thunderbird is to copy the files in the profile directory. But, and this is the neat thing, since the two programs can use the same prefs.js, you can just copy the one file (well, almost, more below) and then Thunderbird will share the folders with Mozilla Mail.

However, that doesn't copy over the Mozilla address book, so there's the potential for version skew there. I haven't been able to get Thunderbird to install the Canadian English spell-checker. Ironically, it was the broken spell-checker in Mozilla that finally prompted me to switch to Thunderbird, but while trying to get it to install in Thunderbird I managed to figure out what was wrong with it in Mozilla (silly UI design will sit there saying "no dictionary" when one is installed, waiting for you to select that one).

The download manager seems to be a giant leap backward. Beyond the dubious "default to saving to the desktop" behaviour (who does that?) It's incredibly slow to display, and doesn't give you any metadata about the downloads (e.g. size, location, etceteras). I was hoping there was an extension that would give me back the Mozilla one, but didn't find it.
