Sync issue - all extensions lost

I was logged in to my Firefox account and was syncing with other devices, so I thought I was all set .

I formatted my C drive and reinstalled windows, but logging back into a fresh install of Firefox, none of my extensions showed up. Bookmarks and History, yes. But no extensions.

I've lost them and now I don't even remember what they were. Is there a way to check the history in my account to determine the lost extensions?

被選擇的解決方法

You can check what data is in the Sync cloud for your Mozilla Account using the About Sync add-on:

https://addons.mozilla.org/firefox/addon/about-sync/

After you install the add-on, you can type or paste about:sync in the address bar and press Enter to load it. The page shows each category of data currently found in the Sync cloud.

I don't Sync extensions, so I don't know what that section of the page is called, but assuming you find it, does it have a list of your old extensions on the Records list?
