I will build a custom chrome, firefox or edge browser extension


About this gig
Turn a repetitive browser task into a tool you can use in one click. I build custom extensions for Chrome, Edge and Firefox, tailored to the way you work.
Your extension can:
Automate page actions and form workflows
Add custom popups, settings, notifications and browser storage
Extract or organize information from web pages
Connect to REST APIs and external services
I can also debug, improve or extend an existing browser extension. You will receive clean, organized source code using current browser APIs, including Manifest V3 where applicable.
To get started, tell me what the extension should do, which browser you use and share any examples or existing code. For complex or multi-feature projects, message me before ordering so I can recommend the right package.
If custom logos, icons or illustrations are needed, please provide the graphical assets.
