Hmm, did you ever set up a Sync account? Mozilla wouldn't have a copy of your bookmarks or other personal browsing data unless you used the Sync service to store it and/or share it between different installations of Firefox.

Yes I have an account its on this email Email hidden by moderator And it was set up and all my bookmarks was synced there, but after I formatted I tried to sync my bookmarks from my account and nothing was sent to my android device, so all my bookmarks now are gone, I fear that maybe it got deleted from mozilla servers permanently, please help and thanks for reply.

Sorry, I'm not familiar with the reasons that your Sync account would not work in that scenario. Hopefully a Sync expert will have some suggestions in the morning.
