INSTALL

Chromium

• Download and unzip uMatrix.chromium.zip (latest release desirable).
• Rename the unzipped directory to umatrix
  • When you later update manually, replace the content of the umatrix folder with the content of the latest zipped version.
  • This will ensure that all the extension settings will be preserved
  • As long as the extension loads from same folder path from which it was originally installed, all your settings will be preserved.
• Go to chromium/chrome Extensions.
• Click to check Developer mode.
• Click Load unpacked extension....
• In the file selector dialog:
  • Select the directory umatrix which was created above.
  • Click Open.

The extension will now be available in your chromium/chromium-based browser.

Remember that you have to update manually also. For some users, updating manually is actually an advantage because:

• You can update when you want
• If ever a new version sucks, you can easily just re-install the previous one

Firefox

Although uMatrix is a restartless addon, I found that installing a newer version over an older one often will glitch the installation. These steps always worked fine:

• Download uMatrix.firefox.xpi (latest release desirable).
• Uninstall current uMatrix if already installed
• Quit Firefox completely
• Launch Firefox
• Drag and drop the previously downloaded uMatrix.firefox.xpi into Firefox

uMatrix settings are kept intact even after you uninstall the addon.

On Linux, the settings are saved in a SQlite file located at ~/.mozilla/firefox/[profile name]/extension-data/umatrix.sqlite.

On Windows, the settings are saved in a SQlite file located at %APPDATA%\Mozilla\Firefox\Profiles\[profile name]\extension-data\umatrix.sqlite.
