The Mozilla Review-Ready Framework
Building a Firefox extension is not about copying a Chrome build. It is about meeting Mozilla’s stricter add-on review requirements from the start.
Scoping is managed using our Mozilla Review-Ready Framework, which filters every feature request through three checks before it reaches addons.mozilla.org.
AMO Guidelines Fit
Having submitted extensions to Mozilla’s add-on store before, we know which patterns trigger manual review delays and design around them early.
Privacy-First Permissions
Firefox users expect stronger privacy defaults, including Enhanced Tracking Protection and container tab support, so we request the minimum permission set and explain clearly why each one is needed.
Cross-Platform Consistency
We test extensions across Windows, macOS, and Linux together, since Firefox is supported on a wider range of platforms than most competing browsers.
Firefox Extension Development Solutions for Every Stage
As a Firefox extension development company, EnactOn supports founders and product teams from initial scoping through Mozilla Add-ons publishing and long-term maintenance. Whether you are starting from an idea, porting an existing Chrome extension, or hiring a dedicated Firefox extension developer, we provide the right engagement for your current stage.
Custom E-Commerce Integrations
We tailor every aspect of your extension, from personalised product recommendations to core features and specialised functionality your platform needs.
Cross-Platform Support
Whether you need it to work only in Firefox or across multiple browsers, we design and build it to work everywhere you need it.
API and Web Service Integration
We ensure smooth integration with your APIs, payment gateways, or any other third-party service your business relies on daily.
User-Centric Platform Design
We focus on building extensions that are easy to use, visually appealing, and intuitive for the people who rely on them.
Post-Launch Support and Maintenance
Our team is here to help even after your extension is live, with ongoing support, updates, and improvements as Firefox evolves.
Dedicated Firefox Developer
Hire an experienced Firefox extension developer who works as an extension of your product and engineering team.
Why Choose EnactOn As Your Firefox Extension Development Company?
At EnactOn, we do more than build extensions. We help businesses reach Firefox users, safely and on time.
Business-Specific Functionality
Off-the-shelf plugins often come with limitations. With a custom-built extension, every feature is tailored to your exact requirements rather than a generic template.
Better Integration With Your Software
A custom extension integrates seamlessly with your existing systems, offering a smoother experience that feels like a natural part of your software.
Security and Customization
Generic extensions often carry unnecessary permissions and security risk. Custom development ensures you only have what you need, built securely around your data.
Ownership and Flexibility
You own the code and have full control. You can modify, enhance, or redesign it at any time without being tied to a third-party vendor.
Why Have 350+ Clients Trusted Us?
EnactOn ships Firefox extensions that pass review on the first attempt and keep working long after launch day.
Proven Delivery Timelines
We respect your launch deadline. Our process is built to deliver your Firefox extension precisely when promised, with no last-minute surprises.
Zero Hidden Fees
We believe in upfront, honest partnerships. You will know exactly where every dollar goes, with no surprise charges once development begins.
Future-Proof Engineering
We build on solid foundations. Your extension is coded to stay compatible with new Firefox releases, not scrapped and rebuilt each year.
Unwavering Post-Launch Support
Our partnership does not end at approval. We stand by our work, providing dedicated support to keep your extension running smoothly as it scales.
Market-Validated Design
We build what real users actually open and use. Our approach is rooted in the way people work inside a browser toolbar, not a lab test.
AI-First Velocity
We combine modern AI tools with senior engineering oversight to accelerate development cycles, getting your Firefox extension to review faster and cost-effectively.
Firefox Development, the Intent-Driven Way
EnactOn’s Firefox extension development combines Intent-Driven Engineering, AI-assisted speed, and strict human oversight. Senior architects define the specification first, engineers govern every implementation decision, and each release passes four quality gates before reaching Mozilla’s review queue.
Define the Intent First
Senior architects convert your extension goals, required permissions, and Mozilla’s guidelines into a clear specification before development begins.
Accelerate Development with AI
AI speeds up coding and iteration, while experienced engineers remain responsible for every technical and product decision.
Keep AI-Generated Code Governed
Raw AI-generated code never enters production. Every output is reviewed, refined, and validated by EnactOn’s engineering team.
Pass Four Quality Gates
Every release is checked for functional correctness, security, performance, and add-on store readiness before it ships.
Apply 13 Years of Experience
Our engineers have built browser extensions, permission systems, and privacy-first integrations handling real users across every major browser.
Take Existing Extensions to Production
Already have a Chrome extension? We port it to Firefox and productionize it instead of starting from zero.
Secure, high-speed products built for business growth
Our software is engineered for speed, security and scalability — delivering dependable performance for businesses of every size.
The EnactOn Firefox Extension Process
Most Firefox extensions stall not because the idea was wrong, but because Mozilla’s privacy requirements were misjudged. Our review-led process eliminates that risk by defining exactly what your extension needs before a single line of code is written.
Discovery and Prototyping
We start by diving deep into your business, your users, and the problems you want a Firefox extension to solve, then move into designing an intuitive experience before any code is written.
Development and Customization
Our Firefox extension developers code the extension, ensuring it is built specifically for your business, and integrate it directly with your existing systems and tools throughout the sprint.
Quality Assurance and Testing
No extension goes live without rigorous testing. We ensure it is fast, secure, and bug-free, running extensive tests to confirm your extension meets the highest standards of performance.
Launch and Support
Once your extension is ready, we launch it and provide ongoing support, whether you need updates, maintenance, or new features down the road.
That extension idea you keep putting off?
You do not need a finished spec. Bring us the idea, the rough notes, and the questions about Mozilla’s review process. We will help you turn it into an extension people actually use.
