Firefox doubled after update. [Windows 10]

Good evening, Today I tried to install an Firefox extension called fast forward, and was met by this message. (image 1) "Please update Firefox to install this extension", it was in the official extensions.mozzila.org website. So I clicked the button, and it downloaded a firefox_installer.exe file, I ran it, and now I have two firefox installations, one in version 108 and the other on 121. I would prefer to use 121 starting today, as it is the versions I use in other computers. But the problem, is that now, the firefox with the version 108 has my user data/settings/bookmarks, while the 121 doesn't and when I try to open the profile folder for my 108 version, windows says there is no such directory, (image 2) I went there by hand, and where firefox states there is my profile, are only the profiles of the 121 installation, since then I restarted my pc (shut off and on, not the restart button), and restarted firefox multiple times, as well as cleaned startup cache. Is it possible that firefox is misrepresenting my profile folder position? Is there a way to save my 108 profile data?

P.S.: I tried using the sync feature and it only downloaded 2 extensions from 8, and didn't download website data. thank you!

I don't know why the second paragraph became a singe line, it says: But the problem, is that now, the firefox with the version 108 has my user data/settings/bookmarks, while the 121 doesn't and when I try to open the profile folder for my 108 version, windows says there is no such directory, (image 2) I went there by hand, and where firefox states there is my profile, are only the profiles of the 121 installation, since then I restarted my pc (shut off and on, not the restart button), and restarted firefox multiple times, as well as cleaned startup cache.
