launch a terminal window by pressing Ctrl + Alt + T, or by browsing for it.
Now access Download folder using CD ~/Downloads Then run tar command tar -xvf firefox-*.tar.bz2 to extract the TarBZ2 archive
Once the files are fully extracted, move them to /opt folder. However, before we can move the files to this directory, you’ll need to elevate your command-line session from a standard user to Root, using the su or sudo -s command.
Now that there is Root access in the terminal use the mv command to place the Firefox system files in the /opt directory of your Linux PC’s filesystem.
Note: Change “username” in the command below with the username on your computer, or the files will not move.
Firefox Developer Edition’s files are in place in the /opt directory on your Linux PC. Still, you won’t be able to launch the browser app or use any of its functions, as the binary isn’t in the right place.
To set the binary in the right place, you must make a symlink from the /opt/firefox/ folder to the /usr/local/bin/ folder using the ln command.
Create desktop shortcut
After putting the Firefox binary in the /usr/local/bin, you’ll need to set up a new desktop shortcut by using the touch command.
With the new desktop file made, we can start editing the shortcut. To modify the file, you must open it up in a text editor.
With the desktop shortcut open in Nano, paste the code below inside of the editor.
[Desktop Entry]
Name=Firefox Developer
GenericName=Firefox Developer Edition
Exec=/usr/local/bin/firefox
Terminal=false
Icon=/opt/firefox/browser/chrome/icons/default/default48.png
Type=Application
Categories=Application;Network;X-Developer;
Comment=Firefox Developer Edition Web Browser
Save the edit with Ctrl + O and exit with Ctrl + X. Then update the permissions of the file with chmod.
With the permissions updated, you’ll be able to access Firefox developer edition in your application menu under “Internet.

Problem:Firefox is very slow when loading a given host for the first time, e.g. www.google.com or www.youtube.comAfter it's done loading, browsing on that domain is ok.Please watch the video (it's on veoh.com) since it's the best way to understand the problem.https://vimeo.com/319319274Some text and web pages content are in italian because of the geolocalization.In the video I use VirtualBox for recording convenience but it's the same behaviour in the host machine.
Ubuntu 18.04.4
Tried:Everything (Ubuntu clean install, reset Firefox profile, proxy settings, disable hardware acceleration, disabling/removing all plugins and extensions, connect to cable - no router).
Important:Chromium and Opera work fine.Therefore this is obviously a bug in Firefox. Of course it may only happen under very specific hardware / network combinations, otherwise one thousand people would lament this problem. So I'm open to give additional information.
