Is there a way to completely uninstall Firefox while saving the bookmarks?

I have been having little issues with FF for ages, such as, for whatever reason, I am unable to use the whisper style on Fluther (trust me when I say it’s only this computer, this particular instance of FF), or that it never asks me if I want to save tabs when I quit, it just does it. So, now there’s a load of little things going wrong, getting bigger, I’m over it and I need to start over completely.

I tried uninstalling and reinstalling FF using the uninstaller, hoping that would fix it, but no dice, same issues. I’m thinking there’s some registry issue or something else going on, but whatever the case, I want to completely uninstall FF (including deleting registry entries), but I have no idea how to save my bookmarks.

I’d rather not start over again, as I’ve built up these bookmarks over a few years. Anyone know how to save them?
