Git Commit Template
Capitalized, short (50 chars or less) summary
More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of an email and the rest of the text as the body. The blank
line separating the summary from the body is critical (unless you omit
the body entirely); tools like rebase can get confused if you run the
two together.
Write your commit message in the imperative: "Fix bug" and not "Fixed bug"

How to install Firefox Developer Edition on Linux

Download from Mozilla Firefox Developer Edition webpage. Extract it with file-roller and move the folder to its final location. A good practice is to install it in /opt/ or /usr/local/.

Once you moved the files to their final location (say /opt/firefox-dev/), you can create the following file ~/.local/share/applications/firefox-dev.desktop to get a launcher with an icon distinct from normal Firefox.

[Desktop Entry]
Name=Firefox Developer
GenericName=Firefox Developer Edition
Exec=/opt/firefox-dev/firefox %u
Terminal=false
Icon=/opt/firefox-dev/browser/chrome/icons/default/default128.png
