My account and my brother's merged because we used once the same laptop.
Hello; so, my brother lend me his old laptop, clean. I signed in firefox with my account and explore normally. One day, he need it back a couple days so he can work while he repairs his main machine. Log off of my account and log on in his. Now my bookmarks, historial, loggins, etc appear in his session. We think that can not be possible with separate accounts with different associated e-mail and passwords, but here we are.
There is a way to separate my things from his account? It only happens to him, i don't have in my browser his data. Thanks

That happens if you connect a device to a Sync account, data on the Sync server will be merged with data on this device. You should have chosen to remove data that came from Sync then you disconnect this device. Possibly your brother hadn't connected this device to his Sync account before, but if he connected to his account when your data was still on this device, then your data will be uploaded to his Sync account. This would have to be cleaned up locally and you should be careful reconnecting this device once again to your Sync account.
Thanks for the reply.
Is there a solution to delete my data from his account, like a backup?
For the bookmarks there are backups in the bookmarkbackups folder, so you can restore an earlier backup from before you synced.
Other data you need to cleanup manually.
