About this gig
Please message me before ordering. I only send custom offers after we agree on your requirements, supported browsers, price and delivery time.
I can create a complete custom browser extension from scratch, add features to one you already own, or fix bugs and compatibility issues.
I can help with:
- Chrome, Brave, Edge and Firefox extensions
- Popups, sidebars, settings pages and custom interfaces
- Tab management, shortcuts and productivity tools
- Website enhancements and repetitive task helpers
- API connections and data handling
- UI improvements, updates and troubleshooting
Tell me what you want the extension to do, which websites it should work on, and which browsers you use. I'll review the idea and send a custom offer for the agreed work.
Delivery includes your extension source files, setup instructions and testing on the agreed browsers. Firefox extensions can be submitted for private, unlisted signing. Public browser store submissions are not included.
Prices start at $15; the full quote depends on your requirements. One-day delivery is available for agreed work. Larger builds need an agreed timeline. Unlimited revisions cover the agreed features.

Hi, I'm Andre. With 19 years of experience, I help people get their PCs and websites working properly.
I troubleshoot Windows 11 and 10, remove malware, improve performance, and set up software, VPNs and privacy settings. I also install CodeCanyon scripts and fix or customize websites using cPanel, PHP, Laravel, MySQL, HTML, CSS and JavaScript, including SSL issues.
I explain what I'm doing, answer your questions, and keep you involved throughout the job. I speak English and German.
Message me with your requirements first. We'll agree on the work and price before I send a custom offer.

FAQ
Should I contact you before ordering?
Yes. I only send custom offers after reviewing your idea or existing extension. Tell me the features, target websites and browsers so we can agree on what is possible, the full price and delivery time before work starts.
Which browsers can you develop extensions for?
Chrome, Brave, Microsoft Edge and Firefox. We agree on the target browsers and versions first. Some features differ between browsers, so support for every browser is not automatic; I test the browsers included in your offer.
Can you fix or upgrade an existing extension?
Yes. I can review bugs, add features, improve the interface and update compatibility. Please send the source files you are entitled to modify, steps to reproduce the issue, and your expected result so I can assess the work first.
How are the price and delivery time decided?
Prices start at $15. I quote the full project after reviewing your features, browsers, websites and any integrations. Complete extensions are welcome. One-day delivery is available for agreed work; larger builds have a delivery schedule agreed before the custom offer.
Will I receive the source code and installation instructions?
Yes. Delivery includes the agreed extension source files and instructions to install and use it, plus testing on the browsers in your offer. Existing third-party libraries and assets keep their own licenses.
Do you publish extensions or handle Firefox signing?
I do not submit extensions for public browser store listings. For Firefox, I can submit the extension for private, unlisted signing so it can be installed as a signed extension. Any signing review is handled by Mozilla, so its approval and timing are outside my control.
Does my extension need hosting, APIs or special permissions?
It depends on the features. Many extensions work locally; others need an API, account, database or backend. We discuss permissions, data handling, hosting and any paid services before the offer. Third-party charges are not included unless explicitly agreed.
What is included in unlimited revisions?
Revisions cover adjustments and fixes to the features agreed in your custom offer. New features, additional browsers, changed workflows or later third-party website changes need a separate agreement. Tell me your requirements first so the scope is clear.
