Beijing Mozilla Online Ltd, a.k.a. Mozilla China, is a limited company to help promote and deploy Mozilla products in China. Similar to Mozilla Corporation, Mozilla China is a for-profit company funded and created by a non-profit organization. Mozilla China was founded on March 4, 2005. It is a wholly owned subsidiary of the Mozilla Corporation. Mozilla China is co-chaired by Dr. Li Gong of Sun Engineering and Research Institute and Mr. Mingshu Li of Institute of Software, Chinese Academy of Sciences, both of whom will sit on the steering committee with Mitchell Baker, president of the Mozilla Foundation. Mozilla China built a Chinese version of the Mozilla web site, provides technical and architectural direction for Mozilla development in China, organises and operates discussion forums, and further develops Mozilla source code in China.

## How to interpret this page

Estimated down reports are based on US problem-related activity. Values are relative activity from 0 to 100, not counts of submitted reports. The HTML chart averages samples into ten-minute intervals. Partial samples are excluded and missing samples are not invented.

Recorded outage reports and estimated activity are separate signals. Neither confirms that every user is affected. Missing or stale data does not establish that a service is working.

Methodology: https://iszdown.com/methodology

## Citation

Cite [Mozilla China on Iszdown](https://iszdown.com/now/firefox), include your access time and the observation time above, and qualify estimated activity as an estimate. Recheck before describing current status. Iszdown is independent of the monitored provider.

## Estimated activity samples

No usable activity samples are available for this service in this window.

## Evidence and recovery

Repeated website check failures. Two recent checks of the monitored website endpoint failed. This does not establish that the full app or API is down.

No recent recovery can be established from available evidence.

## Website measurements

Successful sampled checks (24h): 0% (0/128). Restricted checks: 0. Median response: Unknown ms. P95 response: Unknown ms.

These are sampled public website checks from one US server, not continuous uptime or authenticated app/API tests. Missing data stays unknown.


## Daily outage history

Dates use America/New_York. Green means no issues observed with sufficient monitoring; pink means official incidents, repeated website failures, or reports from at least three network addresses. Gray means insufficient coverage. These are daily evidence summaries, not guaranteed uptime.

## About Mozilla China monitoring

This page combines the available Mozilla China report activity, official product status, public website measurements, and daily history. Each measurement has its own observation time. A search spike alone does not confirm downtime, and a reachable website does not establish that sign-in or every product feature works.

## Troubleshooting

### Mozilla China will not open

Compare your usual browser or app with a private browser window, then try another network if available. Save unsent work first. A difference between networks can help separate a local connection problem from a wider disruption.

### Mozilla China is slow or only one feature fails

Record the affected action, exact error, and time. Compare the website response measurements with any official component incidents; loading a homepage does not test every feature.

## Frequently asked questions

### Is Mozilla China down right now?

Repeated website check failures. Two recent checks of the monitored website endpoint failed. This does not establish that the full app or API is down. This page was assembled at 2026-11-08T18:28:57.000Z.

### How many Mozilla China outage reports are there today?

The displayed rolling 24-hour window contains 0 recorded reports, from 2026-11-07T18:20:00.000Z to 2026-11-08T18:20:00.000Z. This is not a calendar-day total or a count of affected people. Estimated activity is shown separately as an estimate.

### Why does Mozilla China show operational when it is not working for me?

An official operational status can coexist with a local network issue, account problem, or feature-specific incident. Compare the mapped components, recent incident updates, and regional diagnostic on this page. Automated website checks test public access, not your signed-in session or every Mozilla China feature.

### When was Mozilla China status last updated?

No current product status observation is available for Mozilla China. Reports, estimated activity, and website checks can provide additional context.

### Has Mozilla China had outages before?

The daily calendar links available incident evidence and retains daily monitoring summaries. Pink marks service issues, green requires sufficient observations with no issues observed, and gray means insufficient coverage. The collected history is incomplete and is not a lifetime outage count or a guarantee of uninterrupted uptime.

### How do I follow Mozilla China or report a problem?

Use “Watch this service” to save Mozilla China in this browser’s watchlist, then return to compare its status with other saved services. Optional browser notifications can flag status changes while the watchlist page stays open and visible; background alerts are not sent. Use the problem-report button for an outage report; contact the provider through its official website for account, billing, or private support issues. Iszdown is independent and cannot resolve provider support tickets.
