If your looking to find top developer resource, Lemon.io is the place.

Lemon.io has been a game changer for us. Speed, clarity, and quality were there from day one, but what really impressed me was how much they care about getting the right fit, not just filling a role.

We had some specific requirements, and the candidates surfaced were consistently high quality and well aligned. The team checked in regularly, handled onboarding smoothly, and genuinely went the extra mile to keep things simple.

It’s rare to find a service that combines great talent with great people. Lemon.io absolutely does both, and we’ll be continuing to work with them. Diana is a superstar.

Lemon cares a tremendous amount about finding high quality developers that are the right long term fit. We had some specific requirements and Iryna was able to find some great options that were all really qualified. They checked in several times during the engagement and made sure the start and kickoff for the dev was well handled. Will be planning on working with them well into the future.

Building our tech startup would not have been possible without Lemon.

We’ve been working for ~1.5 year with one of their full stack engineer from Brazil, Matheus, whom we strongly recommend. As 2 co-founders looking for moving our prototype product to a production level, Lemon has been amazing at guiding us through the selection process and then ongoingly whenever we had any questions or requests (thank you Andrew Bondar) – definitely recommend.

FAQ about hiring Firefox extension developers

Where can I find Firefox extension developers?

To hire Firefox extension developers, post a job on Indeed, Glassdoor, or LinkedIn sites. Another option is to browse freelance platforms (Upwork, Fiverr, etc.) or developer forums like GitHub, Stack Overflow, or Mozilla Add-ons Developer Hub. But here’s the tricky part: you’ll still need to screen all the applicants, narrow down the best ones from potentially hundreds of submissions, and schedule multiple interviews for each.

All of this can be overwhelming, especially if you’re unfamiliar with what’s under the hood of the Firefox extension or are not used to hiring independently. That’s where Lemon.io comes in — we can help by sending you a few pre-screened, highly qualified candidates who match your needs perfectly, and we can do it in under 48 hours. Just meet them, pick the one you connect with, and get started!

What is the no-risk trial period for hiring Firefox extension developers on Lemon.io?

When you hire a Firefox extension developer through Lemon.io, there’s no rush to make an immediate commitment. We offer a no-risk trial period, where you get up to 20 paid hours to collaborate with the developer on actual project work that shows how well they fit your needs.

And don’t worry, you’re fully protected. If the developer doesn’t meet your expectations, our zero-risk replacement policy guarantees we’ll quickly find a suitable replacement with minimal disruption to your project timeline. It’s rarely necessary, but we’ve got you covered if it happens.

Is there a high demand for Firefox extension developers?

Yes, there’s definitely a good demand for Firefox extension developers. Firefox’s mainly dedicated user base values privacy and customization. Because of this, developers who can craft extensions that add value to the browsing experience, whether it’s enhancing productivity, improving security, or offering unique features, are needed. As the browser continues to evolve, the market for well-crafted, useful Firefox extensions remains strong, keeping developers in this space in demand.

How quickly can I hire a Firefox extension developer through Lemon.io?

You can hire a Firefox extension developer within 48 hours. We aim to deliver you a list of hand-picked candidates right away after we go over your needs. After that, you can manage the timeline as you see fit, whether adding extra discussions or steps, which might take a few more days. However, it’s pretty common for clients to have their new Firefox extension developer ready to start working on their projects within less than a week.

What are the main strengths of Lemon.io’s platform?
