If you need to contact Mozilla Firefox support, the first thing to know is that there is no phone number or direct email for general user inquiries. Instead, the official and most effective way to get help is through the Mozilla Support website, which connects you to a vast knowledge base and a community of experts.
How to contact Mozilla Firefox support: what you need to know first
Mozilla does not offer a customer service phone line or a general-purpose email address for Firefox. Attempting to call or email will only lead to dead ends. The only official channels are the Mozilla Support website, community forums, and social media accounts. This means that if you run into a problem, your first stop should always be the support portal, where you can search for solutions, ask questions, and get help from both volunteers and Mozilla staff.
Get help on the Mozilla Support website
The Mozilla Support website is the central hub for all Firefox help. It hosts a comprehensive knowledge base with articles written for Firefox on desktop, Android, and iOS. To use it effectively, start by typing a few keywords that describe your issue into the search bar. For example, if you are having trouble with tabs, search for “tabs not working” or “restore tabs.” The search results will show you relevant guides and step-by-step tutorials. Before posting a new question anywhere, always check if an existing article already answers your problem, this is the fastest way to resolve common issues.
Ask the community on the Mozilla Support forum
If the knowledge base doesn’t solve your problem, the Mozilla Support forum is your next step. This is a place where you can post a question and receive answers from a community of experienced users and Mozilla staff. When you create a new thread, be as specific as possible. Include your Firefox version (found in the “About” section of the Help menu), your operating system, the exact error message you see, and any steps you have already tried. Screenshots are also extremely helpful, you can attach them directly to your post. The more context you provide, the faster and more accurate the responses will be. Engage politely with anyone who replies, and mark the answer that solves your issue as “solved” to help future users.
Reach Mozilla Firefox on social media
For a more direct line of communication, you can reach out to Mozilla Firefox on social media. The official @FirefoxSupport Twitter handle is dedicated to helping users with Firefox on desktop, Android, and iOS. This is a good option if you prefer a quick, public interaction or if you want to share a screenshot or video of a bug. While you won’t get a phone call, the team monitors this account regularly and often responds with troubleshooting steps or asks for additional details. For general news and updates, you can also follow the main @Firefox account.
Report a broken site or submit feedback
If you encounter a website that doesn’t work correctly in Firefox, you can report it directly from the browser. Click the menu button (three horizontal lines) in the top right corner, then select “Report broken site” at the bottom of the menu. This tool sends a report to Mozilla’s engineers, including technical data about the page and your browser, which helps them identify and fix the compatibility issue. Similarly, if you have suggestions for improvement or want to share a positive experience, go to the Firefox “Help” menu and select “Submit Feedback...”. This opens a form that goes straight to the Firefox product team, so your voice is heard.
Report a bug using Bugzilla
When you find a genuine bug in Firefox, something that crashes, freezes, or behaves incorrectly, you should report it using Bugzilla at bugzilla.mozilla.org. This is the official bug-tracking database used by Mozilla developers. Before filing a new report, search Bugzilla to see if someone has already reported the same issue. If they have, you can add a comment or vote for it instead of creating a duplicate. If not, you can file a new bug. To make the report useful, use the latest nightly build of Firefox to see if the bug still exists, and include detailed steps to reproduce the problem, your operating system, and any error messages. Providing this information helps developers pinpoint the cause and fix it faster.
