Can you install the Developer version and Stable version of Firefox on the same Windows, or Linux or Mac account?
I used to have a Dev and Stable version of Firefox on a single Windows account without any obvious problem.
That does not work with Linux (ubuntu 15.04) without extra steps. I ended up replacing stable Firefox which was not my intention.
https://www.mozilla.org/en-US/firefox/developer/ does not highlight the possible issue.
If there is an issue on Linux/Mac/Windows(?) the web page should highlight the issue.
Additional System Details
- Shockwave Flash 11.2 r202
- This plug-in detects the presence of iTunes when opening iTunes Store URLs in a web page with Firefox.
- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0
See if this guide helps you.
There are currently three ways to do this, manually, PPA or Ubuntu Make:
Download from here: Firefox Developer Edition — Mozilla
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 Terminal=false Icon=/opt/firefox_dev/browser/icons/mozicon128.png Type=Application Categories=Application;Network;X-Developer; Comment=Firefox Developer Edition Web Browser.
To launch it, search for Firefox Developer, and simply run the firefox binary, and voilà.
Firefox for developers currently resides in Firefox Aurora builds : “Ubuntu Mozilla Daily Build Team” team. It should be noted that:
Firefox Developer Edition replaces the Aurora channel in the Firefox Release Process. Like Aurora, features will land in the Developer Edition every six weeks, after they have stabilized in Nightly builds. - Developer Edition - Mozilla | MDN #The_latest_Firefox_features
Version 35.0a2, first offered to Firefox Developer Edition users on November 10, 2014 - Firefox — Aurora Notes (35.0a2) — Mozilla#main-content
Install the Firefox Developer Edition, formerly know as Aurora, like so:
sudo add-apt-repository ppa:ubuntu-mozilla-daily/firefox-aurora sudo apt-get update sudo apt-get install firefox
Due note that installing with the aforementioned ppa, will result in your current Firefox installation being replaced!
Ubuntu Make This method has been provide by Jorge Castro, I am adding this here, because its also an excellent way to install the Firefox Developer Edition(and many others dev tools).
sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make sudo apt-get update sudo apt-get install ubuntu-make
After you have installed ubuntu-make, tell it to install the web tool firefox-dev.

Using the tarballs will be the easiest way to have multiple builds on Linux. Just extract them in own folders (say in /home to make permissions easier for updates) and make sure each is using a separate Profile is the basics as you should not share a Profile.
Note that Beta builds gets say six to twelve builds for a version. Aurora (aka developer edition) and Nightly gets checkins almost everyday so they get updates each of those days. This means there can sometimes be issues until fixed, finished or reverted.
