Last night, I uninstalled Firefox and reinstalled it again this morning. I have sync on with my account, but my pinned tabs are COMPLETELY missing all together and a few settings I had were undone for some reason. I feel absolutely sick right now because I thought everything was supposed to come back once I signed into my account, but it didn't. Syncing pinned tabs was not a listed option in Sync, so I assumed it was just an automatic thing it would do either way. Absolutely any help at all on any level would be so deeply appreciated. I just want my stuff back. Thank you so much in advance.
