# Extensions
The WebDriver BiDi specification provides a flexible framework that allows browser vendors to define custom modules and arguments. This document outlines the Firefox-specific extensions implemented in WebDriver BiDi, including any custom functionality beyond the core specification.
## Modules
There are currently no custom modules defined in the Firefox implementation of WebDriver BiDi.
## Parameters
Firefox provides additional parameters for certain commands, as detailed in the list below.
### webExtension.install
```CDDL
webExtension.InstallParameters = {
extensionData: webExtension.ExtensionData,
? moz:permanent: bool .default false,
}
```
Description:
* `moz:permanent`: When set to `true`, the web extension will be installed permanently. This requires the extension to be signed. Unsigned extensions can only be installed temporarily, which is the default behavior.
