Firefox help

I use Firefox at home and in the office. When I bookmark pages at the office I never lose them even when Firefox updates. At home, whenever Firefox updates itself or every couple weeks I seem to lose my bookmarks. Does anyone know why this happens? Is there a setting on Firefox I am missing?

If you use the Foxmarks Bookmark Synchronizer add-on, your bookmarks will be synchronized across any machines you set up with it. Then you'll never lose them.

Thank you!

That's a weird occurrence. Have you tried reinstalling Firefox?
