User reviews

Users find Web Highlights highly effective and user-friendly for annotating web pages and PDFs, praising its sync capabilities, organization tools, and free availability. The add-on supports research and study by enabling easy highlighting and note-taking. However, some users note it uses memory that can slow down performance temporarily and experiences keyboard shortcut conflicts during note-taking.

Pros

Highly useful for highlighting and annotating web pages and PDFs, aiding in research and study.
User-friendly interface with features like hotkeys and an icon over highlighted text for easy access.
Syncs highlights seamlessly across devices, including between desktop and mobile browsers.
Supports organization through color-coding and a highlights dashboard to quickly review important text.
Free to use with powerful features, praised for being better than many alternatives.

Cons

Consumes some memory and can occasionally slow down internet response times, requiring users to disable it temporarily.
Certain hotkeys like the 's' key conflict with note-taking, making it difficult to use some keyboard inputs within notes.

Recent reviews

This is one of the more useful add-ons that I have used. Like any add-on, it takes up some memory, and on occasion it has slowed down my internet response time on some applications. I simply disable the feature during those times, but it is a valuable tool in highlighting text for the articles and studies that I like to read.

Ever find yourself coming back to a page to reference the important text? Well, highlight it! That way you can see what you wanted to remember at a glance in your Web Highlights dashboard, or even go to the page and find your highlights in the text. The powerful features sweeten the deal even more!

it's great, it works as I expected it to and how I want it to. The only issue is when taking notes if I press the `s` button it toggles the web-highlighter menu on/off. Thus I'm unable to use `s` when taking notes on it.

Extension safety

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.

Web Highlights: PDF & Web Highlighter + Notes requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
