## INSTALL
#### Chromium
- Download and unzip `uMatrix.chromium.zip` ([latest release desirable](https://github.com/gorhill/uMatrix/releases)).
- 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](https://github.com/gorhill/uMatrix/releases)).
- 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` .
