The User Agent Switcher extension adds a menu and a toolbar button to switch the user agent of a browser. The extension is available for Toolkit-based Gecko applications (see the Works in section for more details), and will run on any platform that this layout engine supports, including Windows, OS X, and Linux.
The extension can be installed from from the releases page.
The latest source code can be downloaded as a ZIP file or directly from Github.
The current version should work in any Toolkit-based application using Gecko 7.0 or higher. It’s been successfully tested in:
It should also work in Firefox 7.0 or higher, Pale Moon 24.0 or higher, SeaMonkey 2.4 or higher, and in other applications using Toolkit and Gecko 7.0 or higher, but these haven’t been tested.
Older versions claim to support older 1.x and 2.x versions of Firefox, 1.x and 2.x versions of Flock, and Songbird. For SeaMonkey, 2.0 or higher is needed for it to function in a meaningful way (older versions claim to work in SeaMonkey 1.x, but they don’t).
Of course, I recommend you use a current version of a maintained application if possible, to avoid putting yourself at risk for exploits.
Currently my planned releases are:
