One of the main problems I face while using Chromium is that most of the time downloads break half way and I have to start from beginning. Also, the pause/resume function is poorly supported as it simply fails where Firefox perfectly pauses/resumes downloads with ease.
However, I got the problem solved by using Steadyflow download manager, which we covered only few days back. Now there is a Chrome/Chromium extension for it which allows us to directly download files in steadyflow download manager. Steadyflow also comes with appindicator support for Ubuntu 11.04.
To download Steadyflow, run the following commands:
sudo add-apt-repository ppa:sikon/steadyflow
sudo apt-get update
sudo apt-get install steadyflow
Download Chromeflow Chrome/Chromium extension from here and just drag 'n' drop it on browser window to install it.
