I am trying to load more than one firefox profile at the same time. I use to use the profile switcher plugin to do this but it stopped working after a update a few months ago. I found this question "https://support.mozilla.org/en-US/questions/1184891" which is exactly what I am trying to do but I don't know what they mean by " add the command line argument`-no-remote` in your Firefox executable to launch different profiles in the same Firefox instance. " Please help

Chosen solution

As to the add-ons, Here are your choices; 1) Contact its support and ask if they will update 2) Find a replacement 3) Downgrade to a prior Firefox 4) Do without

Firefox can be run with different profiles at the same time using command switches.

Here is an example; (on one line) C:\PROGRA~1\MOZILL~1\firefox.exe -no-remote -new-instance -new-window -P Firefox_v_57

https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options 

Usage: C:\PROGRA~1\MOZILL~1\firefox.exe [ options ... ] [URL]
      where options include:

 -h or -help        Print this message.
 -v or -version     Print Firefox version.
 -P <profile>       Start with <profile>.
 -migration         Start with migration wizard.
 -ProfileManager    Start with ProfileManager.
 -no-remote         Do not accept or send remote commands; implies -new-instance.
 -new-instance      Open new instance, not a new window in running instance.
 -UILocale <locale> Start with <locale> resources as UI Locale.
 -safe-mode         Disables extensions and themes for this session.
 -console           Start Firefox with a debugging console.
 -jsconsole         Open the Error console.
 -browser           Open a browser window.
 -new-window  <url> Open <url> in a new window.
 -new-tab     <url> Open <url> in a new tab.
 -preferences       Open Options dialog.
 -search     <term> Search <term> with your default search engine.
 -setDefaultBrowser Set this app as the default browser.
