How to remove sync information from computer, which is inaccessible now?
I've had a few computers in Firefox Sync. Operating System was reinstalled at one of them. So now every time I open Tabs From Other Computers I see it there. Is there a way to remove sync information of that Firefox setup from my account without regenerating a new sync key and resetting Firefox Sync again on all computers?

Those tabs should expire automatically.
This may take a few days to take place (tabs expire after a week).
About a month had passed and tabs are still there. :) I don't know why then.
You can try to disable syncing the tabs and wait a few days to see if that works.
Click the "Sync Options" button at the bottom of the Options > Sync window to select what to sync.
I'll try that. Thank you for help!
