When users open multiple environments in batches and perform operations on them simultaneously, they may encounter issues such as long start-up wait times, high memory usage and device lag. The newly introduced SunBrowser Flash is designed to reduce resource consumption and lag when running multiple environments, whilst maintaining data isolation between them.
What is SunBrowser Flash?
SunBrowser Flash or SunBrowser – which should I choose?
If you wish to run multiple browsers simultaneously, or if your device has limited memory or lower-spec hardware, we recommend that you choose SunBrowser Flash.
SunBrowser offers a wider range of customisable settings. If you wish to customise fingerprint parameters and create your very own fingerprint browser, we recommend choosing SunBrowser.
How do I use SunBrowser Flash?
1. To use SunBrowser Flash, you will need to update your JavaScript version and download the specified browser engine.
2. SunBrowser Flash is based on the Chrome engine and is listed alongside SunBrowser and FlowerBrowser, displaying its name, a separate icon and a ‘Beta’ label. Only the latest version of the browser engine is available for download; previous versions cannot be selected.
3.The Flash core version is 152; smart UA matching may assign versions 155 or 156. It is recommended to select a specific UA version first before randomising, as this can further improve the match between the core and the UA version.

2. Configuration and User Agent
The fingerprint configuration is based on SunBrowser; the following items differ:
|
Configuration options |
Visible options and activation rules |
|
|
Retain only ‘Authentic’; selected by default; use the interface language of the current computer; do not display ‘Language-based’ or ‘Custom’.
|
|
Hardware acceleration |
Retain only ‘Default’, with this option selected by default, using the value from the ‘Performance’ setting in [Regional Settings]; do not display ‘On’ or ‘Off’.
|
|
WebGPU |
Leave only ‘WebGL-based’ selected; this is the default setting and will take effect immediately.
|
|
Browser settings |
Only ‘Use global settings’ is retained; no independent environment-level settings are provided.
|
|
Launch Args |
Hidden; user customisation is not supported |
|
|
Not displayed; actually set to ‘Off’ |
|
The above restrictions do not apply to SunBrowser and FlowerBrowser. |
|
3. Downloading and opening the kernel
The kernel can only be downloaded via the ‘New Profiles’, ‘Edit Profiles’ or ‘Modify Fingerprint’ pop-up windows; the rules are the same for both Windows and macOS.


Whether the software is not installed, the version is out of date, it is currently being downloaded, or the download has failed, none of these will prevent you from creating, editing or submitting content.
Both single and batch opening operations require a check of the platform and client versions, as well as the local kernel status; a prompt may appear requesting an update or download.

4. Profiles、Closing and Cached Data
Profiles uses separate open icons to distinguish between SunBrowser and FlowerBrowser
SunBrowser Flash has an icon featuring a small lightning bolt.


Cache viewing, clearing, backing up, restoring, local backups and other cache management features are not supported.
