    I'm a full stack developer with a strong specialization in browser extensions. I built a browser extension startup called Decision Assistant which was acquired after 5 months for $400K. I've worked on more than 50 extensions and have developed my own templates, toolkits, and SDK's to make building extensions a faster, more efficient process. I never look at challenges as being impossible, I find solutions. I don't overcomplicate and I'm efficient with my time. My rate is a bit higher than the average on this platform but my experience allows me to be highly productive and avoid making mistakes and going down rabbit holes. I offer high quality work products that are well optimized and can generally complete any project no matter how complex or challenging it may seem.

At A Glance: Firefox Plugin Developers

Firefox is a free-to-use open-source web browser developed and distributed by the Mozilla Foundation. Firefox has become one of the most popular and widely used web browsers available today, acting as the primary desktop browser for up to 19 percent of worldwide users. The modification and customization of Firefox for a variety of professional or personal uses has become widespread, and through the use of the Internet, these specialized customizations โ€” known as plugins and extensions โ€” can be made available for anyone to take advantage of. Firefox plugins allow for additional features to be integrated into your web browser from other sources for a variety of reasons, such as searching or integrating Adobe Flash.

Firefox plugin developers and programmers can work with you and your business to integrate custom features directly into the Firefox web browser. Developers and programmers are highly skilled and have general expertise and experience with a wide variety of different third-party applications that may already have plugins for Firefox already developed for them. If you are looking to incorporate software that already has plugins, or create a plugin for an entirely new service or feature, both developers and programmers are available to work independently or as part of a team to accomplish your goals. Working with a freelance Firefox plugin developer or programmer on Upwork is a powerful way to implement highly customizable features into your web browser for any imaginable use, either for professional development or personal pleasure.
