Yeah.Maybe use titanium backup to make a backup of the browser. If it doesn't work with the Rom you're going to Flash maybe use a third party browser like dolphin and copy and past the bookmarked links to it. Then back it up with titanium backup. After that restore and you should be set.

I'm also going to suggest making at least two backups, one on local media and one online (removable SDcard or a computer, and then to your email or some service like Dropbox). I doesn't hurt to actually can do a restore test too. If you can actually retrieve your data you need to come up with a better solution.
