Gemma, you should be able to export your bookmarks, save the file, transfer it to the new laptop, and then import them. Go to bookmarks -> organize and it's up at the top under import and backup.
I'm sticking with FF until I run into problems. I haven't had any issues, even with the latest version I just updated to last week or so, so I'm sticking around. I don't think my FF is slow, so I have no need.
I have heard lots of good things about chrome though, so I'm not surprised you love it
