Manage and switch between multiple proxies quickly & easily.
The project is available as a Chromium Extension.
Firefox Addon (Experimental)
There is also an experimental WebExtension port, which allows installing in Firefox Nightly Version >= 56.
Since the WebExtensions API is still under heavy development on Mozilla's side, we strongly recommended using the Nightly channel (>= 56.0) and update frequently.
The Developer Edition and Beta channels will not receive fixes as often and therefore unsupported by SwitchyOmega. Some users report that it works with the Firefox Developer Edition (>= 55) as well, but we strongly advise against doing so. It won't work at all in Firefox 54 Stable.
Please make sure that you are using the latest Nightly build before you report issues. Build number AND build date should be mentioned somewhere in the issue.
NOTE: PAC Profiles DO NOT work on Firefox due to AMO review policies. We will see what we can do.
This project contains a PAC generating module called
omega-pac, which handles
the profiles model and compile profiles into PAC scripts. This module is standalone
and can be published to npm when the documentation is ready.
omega-target contains browser-independent logic for managing the
options and applying profiles. Every public method is well documented in the comments.
Functions related to browser are not included, and shall be implemented in subclasses
omega-web is a web-based configuration interface for various options and profiles.
The interface works great with
omega-target as the back-end.
omega-web alone is incomplete and requires a file named
containing an angular module
omegaTarget. The module contains browser-dependent
code to communicate with
omega-target back-end, and other code retrieving
browser-related state and information.
omega-target-chromium-extension/omega_target_web.coffee file for an
example of such module.
omega-target-* folders should contain environment-dependent code such as
browser API calls.
Each target folder should contain an extended
OmegaTarget object, which
contains subclasses of the abstract base classes like
Options. The classes
contains implementation of the abstract methods, and can override other methods
A target can copy the files in
omega-web into its build to provide a web-based
configuration interface. If so, the target must provide the
file as described in the Options manager section.
Additionally, each target can contain other files and resources required for the target, such as background pages and extension manifests.
For now, only one target has been implemented: The WebExtension target. This target allows the project to be used as a Chromium extension in most Chromium-based browsers and also as a Firefox Addon as mentioned above.

Building the project
SwitchyOmega has migrated to use npm and grunt for building. Please note that npm 2.x is required for this project.
To build the project:
# Install node and npm first (make sure npm --version > 2.0), then: sudo npm install -g grunt-cli bower # In the project folder: cd omega-build npm run deps # This runs npm install in every module. npm run dev # This runs npm link to aid local development. # Note: the previous command may require sudo in some environments. # The modules are now working. We can build now: grunt # After building, a folder will be generated: cd .. # Return to project root. ls omega-chromium-extension/build/ # The folder above can be loaded as an unpacked extension in Chromium now.
grunt watch, run
grunt watch once in the
This will effectively run
grunt watch in every module in this project.
