The Awesome Highlighter Story, 2008 to 2026

What the tool did

In 2008 sharing a web page meant sending a link and hoping the reader found the relevant paragraph. The Awesome Highlighter fixed that with a bookmarklet and a Firefox add-on. You selected text on any page, it turned yellow, you pressed Done, and the site saved a copy of the page with your highlights and gave you a short link (/page/display/...). Whoever opened the link saw the page as you had marked it. It was free, it needed no account for basic use, and it worked on any site. Its tagline was "be nice, highlight".

The install page (/user/welcome/) offered the bookmarklet for every browser and the add-on for Firefox, then the most popular browser among the tool's audience. Registered users got a list of their highlights at /highlights/view and view counts for each shared page. There was a small blog. That was the whole product.

Who used it

The press noticed first: Lifehacker (which linked to it nine times over the years), Mashable, TechCrunch, Cool Hunting and Trend Hunter all covered it in 2008 and 2009. Then educators took over. Ed-tech blogs listed it among free classroom tools; library research guides at UCLA, Virginia, Indiana, Georgia State, VCU, TCU, the National University of Singapore, KU Leuven and many others recommended it to students; digital humanities projects surveyed it as an annotation tool. It travelled far beyond English: Swedish, Spanish, Portuguese, Chinese, Taiwanese, Vietnamese, Persian, Hungarian and Russian blogs all explained how to use it, and the Swedish description ("mark interesting content on websites and share it") became one of the most common anchors pointing at the site.

Why it disappeared

Nobody announced a shutdown. The saved-copy model was expensive to run for a free product (every highlight meant storing a page) and increasingly awkward as sites moved to logins, dynamic content and HTTPS. Firefox's 2017 retirement of its old extension system would have killed the add-on regardless. By 2015 the service had stopped responding; by 2016 every deep address returned an error. The saved pages, and with them every shared highlight anyone had ever made, were gone. The shared highlights archive records what we can still learn about the most-linked ones from the sites that pointed to them.

The domain between owners

After the registration lapsed the domain passed through the expired-domain market. Between roughly 2019 and 2025 it hosted Indonesian gambling pages and was listed by link brokers; thousands of spam links were pointed at it in that period. None of that content or those links have anything to do with this site. Those spam addresses now return a permanent "gone" response, and the spam links are being disavowed.

The 2026 relaunch: what is kept, what is changed

The relaunch keeps the name, the tagline and the job, and changes the architecture. Text fragment links, a web standard shipped in every major browser between 2020 and 2024, do what the old service did without a server in the middle: the link itself tells the browser what to highlight. The new bookmarklet builds those links from your selection; the generator builds them from an address and a sentence. Around the tools sits the reference material the old site never had: how to highlight on every device and format, which extensions are worth trusting, and how to highlight in a way that actually helps you learn.

If you arrived from an old link

• Links to the install page (/user/welcome/) and the add-on file now go to the bookmarklet.
• Links to the highlighter (/page/highlight) go to the link generator; if the old link carried a page address, it is filled in for you.
• Links to shared highlight pages (/page/display/...) go to the archive, at the row for that page where we have one.
• Links to old images and files come here, to the history.
