I'd really like to use the "ungoogled-chromium"-browser alongside firefox- but as a portable version. This mean: All the necessary files are stored in one folder and/or subfolders, so that I can move the folder whereever I want and run it from this location without losing the browser cache, settings and so on ..
For example to switch between ubuntu computers.

If you take a look on the download site, the linux download-file is already called "portable". But if I extract the file and run the browser, it creates folders in my user-directory for example in .config, .cache

I saw a post, where someone helped a user with creating a script, who wanted a portable version of chrome. Is something like this maybe also possible for this ungoogled-chromium..? Or another way? It would mean a lot to me :)

Thanks for any help or information anyway!
