Why can't I run firefox developer and firefox quantum at the same time?
Hello,
I can run Firefox Developer 59.0b4 64bit and Firefox Quantum 58.0 64 bit on my desktop, but I cannot run the same browsers on my laptop. Both my laptop and desktop are HP and 64 bit. Any suggestions would be greatly appreciated.
Thanks

You can use two desktop shortcuts, one for each Firefox version and specify the profile folder via the -P parameter. Add the "-no-remote" command line switch for the Firefox version you do not want to be the default browser because you can't open external links in a Firefox instance opened with -no-remote.

Open Developer Edition, type about:preferences in the URL and press enter. Then check the box that says: Allow Firefox Developer Edition and Firefox to run at the same time. Then Restart!
Thanks Mkll, but I did try that and it didn't work for me.

Thank you both. Everything working well now!
