Is EqualFill: Free Text Expander safe?

Low risk

EqualFill lets page-generated equals-key events trigger requests to local helper services.

EqualFill runs its content script on all sites and frames, watches keydown events, and fetches two fixed localhost URLs when it sees the equals key. The handler does not require the event to come from a real keypress, so a webpage script can dispatch the same key event and cause those localhost requests.
