1) Try restarting your computer.
2) Check your database integrity in the Advanced pane of the Zotero preferences.
3) Disable all your other Firefox extensions.
4) Is this on a local drive, or an external/network drive? If the latter, try a local drive.
If not, perhaps try a new Firefox profile, pointing it to your existing Zotero data directory from the Advanced pane of the Zotero preferences.
You could also try the DB Repair Tool anyway, even if you don't seem to have database corruption.
