merge two accounts
Helo, I might have previously set up an account in Firefox. However, I accidentally triggered another account. Now I wonder is there a possibility of merging accounts. In fact there is little more can occur. Two accounts can clone between each other, so that way if I like a friend, I can just give them my account. Or if I am a sys admin, I can give access to all of the people within the org, to have access to a generic account to bootstrap. Similar to the guest account and then everyone can start their private at that point.

While one can quickly remove bookmarks from one account (say to customize a "bootstrap account" like you mention), merging together multiple accounts is not a feature.
To reduce the bookmarks just delete unwanted stuff and sync to an account of your choice.
