# Browsers in TruClient

Different browsers are available to use for recording your TruClient script.

In this topic:

## Supported browsers and browser versions

TruClient supports the following browsers. For supported browser versions, see Supported Protocols.

Browser | Details
--- | ---
Chromium | An open-source Web browser project from which Google Chrome draws its source code. Chromium is recommended for testing applications that run on Google Chrome or the Chromium-based Microsoft Edge.
TruClient Browser | Developed for Windows, based on Mozilla technology. TruClient Browser is recommended for testing applications that run on the Mozilla Firefox browser. The TruClient Browser versions are equivalent to the Firefox versions.

- TruClient - Web scripts are supported in the TruClient Browser and Chromium browser.

  Note: Support for Microsoft Internet Explorer has been deprecated.

- TruClient - Mobile Web scripts are supported in TruClient Browser only.

## Additional browser considerations

TruClient records your actions while you perform a business process on the browser that TruClient displays. To simulate the functionality of a particular browser, choose that browser when recording or replaying a script.

Generally, the TruClient Web protocol adjusts to differences between supported browsers, so you can record on one browser and replay on any supported browser. However, if you record a script in one browser and replay it in a different browser, you might encounter issues in test results and in the test run. For details, see Replaying on different browsers.

### Differences between supported browsers

Some features are supported only in certain browsers. The following table lists features that are supported only in some browsers, and shows which browsers support each feature.

Feature | Chromium | TruClient Browser
--- | --- | ---
Modify browser preferences (see Modify browser preferences) |  |
Responsive design-based application (see Applications with responsive design) |  |

In addition, some known issues and limitations are specific to each supported browser. For details, see Known issues for TruClient protocols.
