I have Firefox set to open on the default home page with 2 rows of shortcuts. After an update yesterday, all my shortcuts disappeared on my work computer. They are still there on my laptop however. I tried to sync, no go. I have tried to re-add the shortcuts manually and it won't save it. It is important that I fix this as I have several tabs open and signed it to different websites that I work with and this saved me a lot of time.

Help!
