When using university computers, I log in to Firefox Sync so that I have access to my bookmarks and tabs from home. When I do, Firefox will ask to save passwords on my home computer and phone again, even though I had it disabled in the past. Is there a solution for this, other than disabling it manually every time?

Thank you for your time. I'm posting this from my personal computer, so I'm unsure what version of Firefox the university PCs run, but if necessary I can find that information.
