Cross-Browser Extension Development
Porting Chrome Extensions to Firefox
While both browsers use the WebExtensions API, there are critical differences in `manifest.json` keys (like `browser_specific_settings`), permission handling, and background script support. Our tool automates these tedious conversions.
Firefox to Chrome Migration
Moving from Firefox to Chrome often involves adapting to Manifest V3's Service Worker architecture if you haven't already. We handle the manifest structure changes so you can focus on logic refactoring.
Why Support Both?
Publishing on both the Chrome Web Store and Firefox Add-ons (AMO) maximizes your user base. Many power users prefer Firefox for privacy, while Chrome dominates market share. Don't leave users behind!
