Notes on Browser Support

Thinkfree Office supports the latest stable release of each listed browser. Using an outdated browser version may result in degraded performance or limited functionality. We recommend enabling automatic browser updates to stay current.

Microsoft Edge is supported in its Chromium-based version (released in January 2020 and later). The legacy EdgeHTML-based version of Edge is not supported.

On iPadOS, both Safari and Chrome are fully supported for viewing and editing. For the best tablet experience, we recommend using Safari as your primary browser on Apple devices.

Unsupported Environments

The following configurations are not currently supported and may produce unexpected behavior:

Internet Explorer (all versions), legacy Microsoft Edge (EdgeHTML engine), browsers running in compatibility or enterprise mode, in-app browsers embedded in third-party applications (e.g., social media apps), and private/incognito browsing on certain mobile platforms may have restricted capabilities.
