I used to be able to save my ADD-ONS by Logging in case of Firefox reloads..

Firefox 設定

I had to totally reload my OS, Firefox, etc as I lost everything and now trying to restore... Before this re-build, I was able to 'login' to a place that I had saved my ADD-ONS by logging in... Now I have recovered most of my ADD-ONS and want to save them to where I saved my previous one. But when I go to the ADD-ON page, I no longer see a LOGIN to save/retrieve my old ADD-ONS.

Did my crash delete my "acct" that saved my ADD-ONS, or did Mozilla do away with that feature?

In recent years, the Add-ons site switched to using your Firefox Account for login. I think the site still allows you to create add-on lists, but I haven't tried it myself.

Oh, if you meant Firefox Sync, it works best for exchanging data (such as the list of installed extensions) between two different "live" Firefox installations. It doesn't always work as a backup.
