For mobile, you could go with [Cromite](https://github.com/uazo/cromite) or a customly cleansed Mozilla Firefox mobile application called [Fennec](https://f-droid.org/en/packages/org.mozilla.fennec_fdroid/).
If you like to use extensions, you need to follow installation instructions on the [chromium-web-store](https://github.com/NeverDecaf/chromium-web-store)
project to install the web store extension.
Ensure to set `chrome://flags/#extension-mime-request-handling` to `Always prompt for install` if you like to have the possibility to just click on the
"Add extension" button in the Chrome Web Store like you're used to do.
