In fact, it makes top posting preferable since Gmail hides all the
bottom posted material. It's still there if you need to read it, but
generally you don't. ;-)
I use Gmail in TB3, but someone asked me about bottom posting in Gmail,
I give to him this solution.
- Use Firefox
- Install Greasemonkey[1]
- Install "(New) Gmail Bottom Posting" Userscript [2].
