I was fully unaware of the tab swiping feature on android, and I’ve been using firefox forever. That’s so useful, oh my god.

If you don’t plan on having it save passwords, you can add the following to the .desktop file your using for the Exec line:

–password-store=basic

The line for my chrome setup for some public computers at work is:

Exec=/usr/bin/google-chrome-stable --password-store=basic %U

So you’d just need to replace the file path to your chromium path and it should work.
