Install Add-Ons from Browser Backup

Hello guys,

I have question regarding Add-On installation from a browser backup.
My brave was bugged and crashed all the time. So I want to reinstall Brave with all the back up files, which I did in the past without a problem.
Now I would like to know if add-ons are also possible to be installed from those files.

Thanks in advance,

AFAIK, it’s not possible for extensions. I’ve always needed to manually install them

Even though the backup of the browser was at a time where several add-ons were installed? I’m curious.
