How do I make Thunderbird more like Gmail?

I have a Gmail account that I access using Thunderbird and the people I e-mail are quite annoyed because Thunderbird changes the formatting of the e-mail so much.

and I

When I am composing a message, the writing keeps on going for a long time, meaning it just continues instead of wrapping at a certain point (when composing, not when sending it out). It doesn't wrap at the assigned character length. It eventually wraps, but I have to expand the compose window so far it doesn't even fit the width of my screen.
