⛽ Topoff

Topoff fills the job application fields that standard autofill always skips.

LinkedIn URL, GitHub, portfolio, work authorization, salary expectations, disability status, veteran status — all the fields that slow you down on every single application.

The problem

Browser autofill handles name, email, phone, and address just fine. But it has no idea what a "LinkedIn URL" field means. Every job application, you're copying and pasting the same handful of URLs and answers by hand.

Topoff fixes that.

How it works

1. Fill out your profile once in the Topoff popup (stored locally — never sent anywhere)
2. Navigate to any job application
3. Topoff automatically highlights matched fields with an inline badge
4. Click a badge to fill that field, or hit Fill All to fill everything at once

Found a job board that Topoff doesn't detect? Have a field it misses?

The easiest way to contribute:

1. Open an Issue describing the site and field
2. Include what the input's name, id, or label text says (right-click → Inspect)

To contribute code:

2. Make your changes in content/content.js (field rules) or popup/ (UI)
3. Test by loading as a temporary add-on in Firefox (about:debugging)
4. Open a pull request
