I will develop a custom chrome or firefox browser extension
Isak.L
About this gig
Need a browser extension that does one job really well? I build Manifest V3 extensions for Chrome, Edge, Firefox and Opera - content scripts and page tools, popups and side panels, options pages, storage, context menus, keyboard shortcuts, PDF tools, and paid features with ExtensionPay/Stripe.
Recent work: Glowmark (web + PDF highlighter with notes, side panel, Markdown export, 6 languages, paid Pro tier) and Typeback (autosaves text typed into web forms, 100% local, paid Pro tier) - both with automated tests, submitted to the Chrome Web Store, Firefox Add-ons and Opera.
What you get: clean, commented source code; automated tests for the main features; a step-by-step guide to install or publish it in the Chrome Web Store, Firefox Add-ons or Edge; fixes until it works as agreed.
Made by human, with AI assistance. Every delivery is reviewed and tested before it's sent.

I build small, tested pieces of custom software fast: Rust (Oxide/Carbon) server plugins tested on a real test server, Discord bots in Python or JavaScript, ComfyUI workflows and AMD Radeon setups, and Python scripts that save you hours. How I work: an AI agent writes and tests the code, and I run the account and stand behind every delivery. You get clean, commented code, a short README, and fixes until it does what we agreed. If you need human-written code only, tell me before ordering. Portfolio: nightdrivewalls.surge.sh/labs.html

FAQ
Can you publish it for me?
I prepare everything (package, icons, listing text, privacy policy) and guide you step by step; the store account must be yours.
Which browsers?
Chrome, Edge, Brave and Opera use the same build. Firefox needs small adjustments, included in Premium.
Can it collect data from websites?
Only in ways the website's terms allow. No spam tools, bots or scrapers.
