Features & Capabilities

Dictionary Lookup

Dictionary Lookup is a Firefox add-on for quickly looking up English definitions from a selected word, the toolbar popup, or a keyboard shortcut. It uses a compact popover inspired by macOS Dictionary while staying within Firefox extension APIs.

Firefox does not expose the same system Dictionary integration that Safari has on macOS, so this add-on fetches definitions from public web APIs instead. Features

Look up selected text from the right-click context menu. Use the keyboard shortcut Ctrl+Shift+Y to look up the current selection. Search directly from the toolbar popup. View definitions in a polished in-page popover. Save words and review recent lookup history. Search History and Saved words from the options/library page. Shows whether a result came from Dictionary or Wikipedia fallback. No analytics or tracking.

Is Dictionary Glance Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Dictionary Glance requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Dictionary Glance is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
