Is there a portable version of ungoogled-chromium for ubuntu?
Solution 1:
AppImage aims to be an application deployment system for Linux with the following objectives: simplicity, binary compatibility, distro agnosticism, no installation, no root permission, being portable, and keeping the underlying operating system untouched.

Download here as an AppImage:
https://ungoogled-software.github.io/ungoogled-chromium-binaries/releases/appimage/64bit/
Download the latest version and run chmod +x /PATH/TO/ungoogled-chromium_<version>.AppImage, create a folder in the same directory as the AppImage named ungoogled-chromium_<version>.AppImage.home to store all the data in there instead of your home directory, then execute it.
