Warning Before Upgrading

Firefox Quantum (version 57) is not compatible anymore with many of previous versions' (v56 backwards) addons. Today (29 November 2017) I can confirm --for example-- DownThemAll! addon is not working. So please consider it by testing Abrowser v57 on LiveCD before upgrading.

Legacy Extensions, the addons that are not working at Abrowser v57/Firefox Quantum

Check Version


$ apt-cache policy abrowser

If your system "repo map" is old, then, you don't see version 57 there. The '***' is the sign of installed version. If that so, you need to Reload the repo map.

Only v56, whereas v57 is already available at server



$ sudo apt-get update

Check Version Again


$ apt-cache policy abrowser

Now, you should see version 57 there. That means the newest version available for your Trisquel 8. See the v57 is now atop of '***' sign, meaning, there is a new version for Abrowser.

Showing that v57 is available (v57 is the Candidate:)



$ sudo apt-get install abrowser

That command will upgrade your Abrowser to v57. You will lost the previously installed version.

Run Abrowser v57


Run Abrowser from desktop menu. Done!

Abrowser 57

Downgrade to v56


If you dislike v57, you can remove it and install back the old v56 from Trisquel 7 "Belenos" repo.
$ echo 'deb belenos-updates main' | sudo tee --append /etc/apt/sources.list
$ sudo apt-get update
$ apt-cache policy abrowser
$ sudo apt-get install abrowser=56.0+build6-0ubuntu0.14.04.2+7.0trisquel49
$ sudo sed -i '/belenos-updates/d' /etc/apt/sources.list
$ sudo apt-get update
