I will develop a custom chrome extension that does exactly what you need
Teddy W
About this gig
Want a Chrome extension that does exactly what you need? I'll build it for you - and it runs right inside your own browser, so there's no server, no monthly fees, and
nothing to set up beyond a one-time install (a simple guide is included).
WHAT I CAN BUILD
-Popup tools (notes, counters, calculators, pickers)
-Buttons or panels added to web pages (back-to-top, reading time)
-Whole-page tweaks (dark mode, font/zoom, hide elements)
-Keyboard shortcuts and right-click actions
-A custom new-tab page (clock, to-do, dashboard)
-Form auto-fill, keyword highlighting, per-site settings-
Connect to a public API (your own key)
HOW IT WORKS
You tell me what you want, I build it, and I send you the files plus a plain-English install guide. It loads into Chrome in about a minute.
PLEASE NOTE
-Built for Chrome (Manifest V3); a Firefox version can be added.
-It activates on pages you open or reload after installing - that's normal.
-I don't build data scrapers, login automation, or anything against a site's rules.
-Site-specific extensions may need a small paid update if that site is redesigned.
Message me before ordering with what you want and I'll tell you honestly if it fits.

Hi, I'm Teddy, a self-taught Python developer from Sweden. I build custom automation, AI agents and bots that handle the repetitive or data-heavy parts of your work.
Most of what I make is n8n automations and AI chatbots, Telegram bots, Chrome and browser extensions, and MetaTrader trading bots.
I also write scripts to connect the apps and APIs you already use.
I used to work in customer service, so I test everything and explain it in plain language. If something isn't possible, I'll tell you before you order, not after.
Message me what you want to automate and I'll tell you if I can help

FAQ
Do I need to know how to code, or install anything special?
No. I send you the extension files and a 1-minute install guide. It runs in your Chrome
Does it run on your computer or a server? Will there be monthly fees?
Neither — it runs entirely inside your own browser. No server, no hosting, no monthly cost
Will it work on every website?
Self-contained extensions (popups, new-tab, shortcuts) work everywhere. Ones that change websites work on normal sites you open/reload after installing — but not on Chrome's own pages (settings, web store), and a "dark mode for the whole internet" can't be perfect on every site. For a specific site,
Can you make an extension that scrapes data / logs into sites / blocks ads?
No — I keep to productivity/feature extensions and don't do scraping, login automation, or anything against a site's terms. Message me and I'll tell you honestly.
Does it work in Firefox too?
I build for Chrome (Manifest V3); a Firefox version can be added as an extra.
Can you publish it to the Chrome Web Store for me?
Yes as an add-on — you'd need a Google developer account (one-time $5 fee); I prep the listing.
