I use Safari on Mac OS Lion, and one behavior I find rather annoying is that it insists on automatically un-gzipping TGZ archives when I download them. It doesn't untar them; it just uncompresses them, which is virtually useless. Ideally, it wouldn't uncompress them at all, but if it would uncompress and untar them I could live with that.

I'm aware that I can uncheck the "Open 'safe' files after downloading" option in Safari to false, but that also means giving up such niceties as PDFs automatically opening when I download them. Is there a more tailored solution?

PDFs typically open in the browser, regardless of that setting. – Gerry Aug 26 '12 at 12:46

Uncheck the, "Open "safe" files after downloading" checkbox in Safari's General preferences.

Safari Preferences

You can create a file that overrides OS X's safe file types. Instructions here. Keep in mind that this is a white list, so you'll have to add the identifiers for file types you do want Safari to automatically open.

Note: these instructions are a bit old, and I can't confirm if this is still the case with Lion and Safari 6 (only on an iPad at the moment), but its worth a try.
