The package manager says it is already the latest version, so would I have to upgrade via getting the source tarballs? Building would be standard "./compile && make" and then "sudo make install," I assume? Also, I'm not sure how to do steps 4 and 7 on that page. I have done the same types of things on Windows, but I don't know how to do it with wine. I'm pretty sure that I have the gecko installation right though (installed via winetricks, and then replaced the gecko folder with the release candidate folder).
