What is support.mozilla.org?
Updated
support.mozilla.org is Mozilla's official user-support website for Firefox and other Mozilla products. It is where you go to read help articles, follow troubleshooting steps, and ask questions in community forums when something in Firefox, Firefox for Android, Firefox for iOS, Thunderbird, or another Mozilla product is not working as expected. It is a help resource, not a download page or a store, so you will not find paid products or shopping there.
What you can find on the site
The site is organized around help content rather than product marketing. Typical resources include:
- Knowledge base articles — step-by-step instructions for settings, features, and common problems, such as changing your homepage, managing bookmarks, or fixing playback issues.
- Troubleshooting guides — diagnostic flows for problems like crashes, pages not loading, or extensions misbehaving.
- Community forums — question-and-answer threads where volunteers and other users respond to specific problems.
- Product-specific sections — content is separated by product (desktop Firefox, Android, iOS, Thunderbird, and others), so the steps match your version.
Because the content is versioned and localized, the article you land on should match your language and product. If it does not, check the product and version selector on the page before following steps.
How to search for a solution
- Go to support.mozilla.org and use the search box at the top of the page.
- Enter the symptom in plain language — for example, "Firefox won't open" or "bookmarks disappeared" — rather than a guess at the cause.
- Open the result that matches your product and platform. Articles usually start with the most common fix and then move to less common ones.
- Follow the steps in order and check the result after each one, so you know which change actually fixed it.
If search does not surface anything useful, the forum is the next step.
How to ask a question
- Use the Ask a question option and pick the correct product and topic.
- Describe what you expected, what actually happened, and what you already tried.
- Include your Firefox version, operating system, and any error text you saw. You can find the version under the Firefox menu (Help > About Firefox on desktop).
- Keep one question per thread; it makes answers easier to follow.
A note on the "Client Challenge" page
If you land on a page that says JavaScript is disabled and a required part of the site could not load, that is a browser-side block, not the help content itself. The page suggests checking your connection, disabling ad blockers, or trying a different browser. In practice, enabling JavaScript for the site, turning off content blockers for that page, or opening it in a clean browser profile usually resolves it. This matters because the knowledge base and forum both rely on scripts to render search and article content.
When the site is the right place to go
Use support.mozilla.org when you want official, product-specific instructions or a community answer for a Mozilla product. Skip it when you need to download an installer (use mozilla.org), report a security vulnerability (use Mozilla's security reporting channel), or get account billing help for a paid Mozilla service, which is handled through that service's own support flow.
