This answer was generated by AI. Please verify critical information. The persistent "finish setup" message usually means the initial sync process hasn't fully completed or verified your account on that specific device. 1. First, double-check that you are signed into the correct Firefox Account by clicking the menu button (three lines) and looking at the "Sync and save data" section at the bottom. 2. If you are signed in, click on that "finish setup" button. It may open a tab asking you to confirm your email or complete a final step like setting up sync encryption. 3. Try forcing a manual sync: go to Settings > Sync > click the "Sync now" button. Sometimes this clears the notification. 4. If it persists, sign out of your Firefox Account completely (in Settings > Sync > Disconnect), restart the browser, and sign back in. This often forces the setup wizard to run correctly and connect your desktop. Sorry if this answer didn't help you.
