Fantasy Sync Assistant is a Firefox extension for competitive fantasy baseball players who mirror their ESPN league on Fantrax. Fantrax's available trending players page becomes accurate only when your Fantrax rosters match ESPN exactly. This extension scrapes ESPN transactions and draft picks into a queue and replays each move on the Fantrax Commissioner pages, keeping your mirror up to date without manual re-entry.

Usage:

1. Save your ESPN and Fantrax league IDs in the popup Quick Links section
2. Navigate to an ESPN Recent Activity or Draft Recap page to scrape transactions into the queue
3. Set the From / To cutoff range to narrow which transactions will be processed
4. Open the Fantrax Commissioner page (Claim/Drop, Trade, or Draft Import) in the same browser tab
5. Press F8 to process the entire queue automatically, or F7 to step through the next transaction one at a time

Features:

• Transaction Queue -- scrapes transactions from ESPN Recent Activity and Draft Recap pages; processed transactions are marked with strikethrough and out-of-window transactions are shown in grey
• Exclude Transactions -- Ctrl+click any queue row to skip it during processing; click again to restore it
• Queue Controls -- search icon filters the queue by player name; reset icon marks all transactions as unprocessed; trash icon clears the entire queue
• Cutoff Range -- From / To datetime fields define the window of transactions to process; click any queue row to set the lower bound instantly; drag across rows to set both bounds; paste ESPN-format timestamps like "Mon Apr 6 6:19 am" and they auto-convert to the correct format
• Auto Run (F8) -- processes the entire transaction queue automatically, navigating between Fantrax pages as needed
• Next (F7) -- processes one transaction on the current Fantrax tab; also stops auto-run while it is active
• Transaction Types -- handles adds, drops, trades, and draft picks; searches for players by name with fallback variants for initials, accents, hyphens, and MLB team disambiguation
• Quick Links -- ESPN and Fantrax league IDs can be saved by pasting a full league URL or just the extracted ID; one-click buttons open the corresponding league page once an ID is saved
• Roster Size -- displays a recommended Fantrax max roster size that accounts for players who were on the Injured List at the time of an ESPN transaction but are healthy when replaying; set Fantrax's max roster size to this number to avoid roster-full errors
