Features & Capabilities

WordGloss gives you fast, inline word definitions without interrupting your browsing.

Select a word on nearly any webpage and WordGloss opens a compact definition card with:

Clear, concise definitions Multiple meanings when available Human pronunciation recordings from Wiktionary/Wikimedia Commons when available Speech synthesis as a fallback when recorded pronunciation is unavailable Automatic language detection Manual language selection Support for multiple languages Fast cached lookups

WordGloss is designed to stay out of the way: select a word, get its meaning, and continue reading without opening another tab.

What WordGloss can access: WordGloss only reads the word you select so it can provide a definition. It may also use the webpage’s language setting to choose the appropriate dictionary.

WordGloss does NOT read or collect: -The rest of the webpage -Surrounding sentences or paragraphs -Your browsing history -Cookies or saved website data -Passwords, account details, or form entries -Clipboard contents -Images, links, or downloaded files

The selected word is sent to DictionaryAPI or Wiktionary to retrieve its definition. Pronunciation audio may also be loaded from Wiktionary, Wikimedia Commons, or another listed audio provider. WordGloss does not contain advertising, analytics, or tracking.

Is WordGloss 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.

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

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

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.

WordGloss is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
