Features & Capabilities

Word Highlighter automatically highlights the words and phrases you care about, everywhere you browse.

FEATURES

Create multiple groups, each with its own text color and highlight color
Choose whole-word/phrase matching or substring matching, per group
Set group priority by dragging (or with ▲▼ buttons) — controls which group wins when the same text could match more than one
Highlighting is case-insensitive and updates live as new content loads, so it works on infinite-scroll feeds and single-page apps
Export your groups to a JSON file for backup, or import a file to restore or share a word list
A master on/off switch in the toolbar popup, plus quick per-group toggles

PRIVACY This extension does not collect or transmit any personal data. All your word lists and settings stay on your device, in local browser storage.

LIMITATIONS Pages that render their content on a <canvas> instead of regular HTML text — such as Google Sheets, and parts of Google Docs — can't be highlighted, since there's no real text in the page for the extension to find.

Is Text Highlight 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.

Text Highlight requires a few sensitive permissions. 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.

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.

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