Common issues
Expansion not firing, autofill missing fields, and other quick fixes.
A shortcut does not expand
Check, in order: the expansion master switch in Settings; whether the site is in Disabled sites; whether the snippet is scoped to a different profile; and whether the shortcut has no prefix, in which case it expands on Tab, not on typing.
FillKit ignores a field on purpose
Password fields, one-time code fields and card number or CVV fields are skipped everywhere, by design. There is no setting to change this.
Autofill misses or misfills a field
Sites change their forms. Open the set, remove the stale field and pick it again on the page; matching is based on the field's stable attributes, so a re-pick fixes a redesign.
I deleted something by mistake
Deletes show a toast with Undo. Restore from there, or import your latest backup from the backup center.
The panel and a page disagree
Content scripts load with the page: after installing or updating FillKit, reload tabs that were already open.
