Browser Extension Development
A good browser extension does one small job well. I build and publish extensions — my own are live on Firefox Add-ons — and can create a custom one for your product, workflow or audience.
What's included
Custom extensions
Extensions that change or add to a website's behavior: hiding clutter, adding shortcuts, automating repetitive steps.
Publishing to the add-on store
Packaging, store listing and getting through the review process, since I've been through it with my own published add-ons.
Lightweight and privacy-respecting
Extensions that request only the permissions they need and stay out of the way of the pages they run on.
Tools & technologies
- JavaScript
- TypeScript
- HTML
- CSS
- WebExtensions API
- Git
Frequently asked questions
Which browsers do you build extensions for?
My published extensions are on Firefox Add-ons. Extensions built on the WebExtensions standard can usually be adapted to other browsers; tell me your target and I'll confirm what's involved.
Can you build an extension for my website or product?
Yes — for example a companion extension that improves how people use your site, or one that automates a task you or your users repeat.
Do you handle the store submission?
Yes, I can prepare the listing and take the extension through the store's review.
