8.5.1 FP2 Mac default browser

We’re having an issue with a user that recently switched to Chrome as their default browser on a Mac (OS 10.5.8), however whenever they click on a link in Notes it still launches FireFox (the previous default browser). I’ve checked browser preferneces in Notes and it’s set to use the default browser. Other apps on the machine are opening Chrome when the user clicks on a link.

Has anyone else seen this behavior? Is there an easy fix? Perhaps a preference file that needs to be trashed?

Subject: Any help?

Can anyone offer any help with this issue?
