Is there a way to delete the server side data and force my local data to sync? I am a Linux user and I have been distro hopping on my Laptop. I have found that some about:config settings have been synced that are causing issues, so I want to delete all my server side data and force an update using my current setup.

I have seen articles about deleting your account and starting over, but that just seems like a last resort type of option. I am looking for an option that would allow me to choose if I want to use the server side data or use my local settings and overwrite the existing settings on the server. Anyone have any idea on how to do that?
