uBlock/dist/README.md

INSTALL

Chromium

• Download and unzip ublock0.chromium.zip (latest release desirable).
• Rename the unzipped directory to ublock
  • When you later update manually, replace the content of the ublock 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 ublock 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

Compatible with Firefox 52 and beyond.

For stable release version

This works only if you set xpinstall.signatures.required to false in about:config.^{see "Add-on signing in Firefox"}

• Download ublock0.firefox.xpi (latest release desirable).
  • Right-click and choose "Save As...".
• Drag and drop the previously downloaded ublock0.firefox.xpi into Firefox

For beta version

• Click on ublock0.firefox.signed.xpi (latest release desirable).

Location of uBO settings

On Linux, the settings are saved in a JSON file located at ~/.mozilla/firefox/[profile name]/browser-extension-data/uBlock0@raymondhill.net/storage.js.

When you uninstall the extension, Firefox deletes that file, so all your settings are lost when you uninstall.

Firefox legacy

Compatible with Firefox 24-56, Pale Moon and SeaMonkey.

• Download ublock0.firefox-legacy.xpi (latest release desirable).
  • Right-click and select "Save Link As..."
• Drag and drop the previously downloaded ublock0.firefox-legacy.xpi into Firefox

With Firefox 43 and beyond, you may need to toggle the setting xpinstall.signatures.required to false in about:config.^{see "Add-on signing in Firefox"}

Your uBlock Origin 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/ublock0.sqlite.

On Windows, the settings are saved in a SQlite file located at %APPDATA%\Mozilla\Firefox\Profiles\[profile name]\extension-data\ublock0.sqlite.

If you want to automatically receive updates for this version, you can also install uBlock Origin Updater.
