How about everything else (history, add-ons)?

None of them,

Have you ever sync them before you reinstalled windows? If you didn't, all of that might be lost unfortunately.

before reinstalling windows. i'm sure. i synced my account

Try logging in to Firefox on a mobile device and check there as well. If nothing shows up, the sync might've failed.

i think i lost all of them. none of them aren't in firefox of my mobile :(

i hate firefox. i hate

Hm, this is a long shot. Although check if you have an alternative 'profile' by following this guide: https://support.mozilla.org/en-US/kb/recover-lost-or-missing-bookmarks#w_i-can-see-only-the-default-set-of-bookmarks-in-the-bookmarks-folder

i created new profile and i try to sync again, but after that, there aren't any things

You're out of luck then I'm afraid. Unfortunately Firefox isn't best known for its online syncing functionality (main reason why I'm still using Chorme half the time).

After reinstalling FireFox and then using synch I thought I lost all bookmarks. Turns out everything is fine, it is all there, I panicked.

I just needed to select "View\Toolbars\Menu Bar" and "View\Toolbars\Bookmarks ToolBar"

Thank you, and I got a lesson in profiles. I'm getting to old for this stuff.

My adblock addon is there or here, everything is cool.

Note that the initial first sync can take considerably long time to finish, so if you didn't wait long enough then your data may not have been uploaded to the Sync server. Sync isn't meant to be used as a backup, but is meant to sync personal data among other devices.

You should always backup valuable personal data to prevent data loss.
