I use Lubuntu on my trusty netbook, it’s become a nicely polished OS over the last few versions however it still has a few rough edges. One of which is defining a preferred browser.
The default browser on Lubuntu is Chromium, the unbranded version of Google Chrome. While it’s nice I’m still a hardened Firefox user and so I keep Chromium installed but I don’t use it unless diagnosing a browser-specific issue.
I have Firefox selected in “Preferences > Preferred Applications” as my default browser, however hyper-links in emails were still insisting on opening up in Chromium, which takes time as it’s rarely pre-loaded when I’m using the computer.
To fix this I ran this command in a terminal:
sudo update-alternatives --config x-www-browser
This provides some options for a preferred browser, I had two for Chromium and a third for Firefox, I entered the number for Firefox and from then on, no more closing unwanted browsers!
