Re: [Trisquel-users] How to install packages downloaded from the web, like IceCat?

I don't think you should be on the look for deb packages to install. Use the  
package repositories that are official and available in the distro.

Sometimes, a developer has made his/her software available as a deb package  
you can download. Mostly, when you see tarballs, they either contain source  
code or precompiled binaries but no installer, so you can run the software  
from the extracted folder if all dependencies are satisfied. Sometimes  
there's a script (program.sh) you should run to put everything in place.
