I use Fedora a Linux software but I have no idea how to lunch firefox developer tools browser on it. SOMEONE HELP ME!
Ctrl + Shift + I
it should be also possible to do
Then open the Tools menu
and Web Developer
I suspect the original poster might mean “How do I launch the Firefox Developer Edition browser?” (downloadable from https://www.mozilla.org/en-US/firefox/developer).
On Fedora, I was able to download the tarball, untar it, cd into the new directory, and then launch it from the command line like so:
curl -L --output firefox-dev.tar.bz2 'https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US' tar xf firefox-dev.tar.bz2 cd firefox ./firefox
Getting it to launch from the GNOME 3 menu would require adding a desktop entry to ~/.local/share/applications/, which might look something like:
[Desktop Entry] Name=Firefox Developer Comment=Developer edition of the Firefox browser Exec=/path/to/firefox-dev/firefox Icon=/path/to/firefox-dev/browser/chrome/icons/default/default128.png Terminal=false Type=Application Categories=Web;
Hope that helps!
