Glasp is now on Firefox. Highlight web articles, PDFs, and YouTube transcripts in four colors, add notes and tags, and summarize any page or video with ChatGPT, Claude, or Gemini. Everything lands in one searchable library and exports to Notion, Obsidian, or Markdown. Sign in on any browser or on the mobile apps and your highlights follow you. Free, and nothing to migrate.

Firebase is the reason a highlight you make in Firefox shows up on your phone a second later. Firestore backs our sync and Auth means signing into a new browser is one tap with an account you already have, so "nothing to migrate" is a real promise rather than a marketing line. For a two person team, not owning that infrastructure is what lets us spend our time on the highlighting experience instead. It has scaled with us from the first Chrome extension to the mobile apps, Kindle sync, and now Firefox.

glasp.co runs on Next.js, and the Firefox extension leans on it more than it looks. Every highlight the extension saves also has a page on the web that renders server side, which is what makes a highlight shareable and findable instead of trapped inside one browser profile. Shipping an extension and a web app as one product is only realistic for us because the web side is not a separate world we maintain by hand.

We ported Glasp to Firefox largely with Claude Code. The hard part of a browser port is not the new code, it is the hundreds of small places where an existing codebase quietly assumes one browser. Claude Code holds enough of our monorepo in context to find those, apply the change everywhere at once, and run the tests on its own. It has been part of our daily workflow for a while now, from tutorials to production code, and this port is the clearest case yet of it doing work we would otherwise have kept putting off.
