With Mozilla latest changes to Firefox we can't use our favorite profile manger add-ons. That's a little inconviniece for the average user but a huge problem to someone who is using multiple profiles to manage multiple projects and constantly in need of changing from one to another.

Luckily there is a super easy option which is even faster than all the previous options were. It needs a bit of preparation but it well worth the pain.

We only need a profile manager shortcut on the desktop and we'll be good to go.

Right click on the desktop and select New > Shortcut.

In the "Type the location of the item" field enter:

"C:\Program Files\Mozilla Firefox\firefox.exe" -p -no-remote

Enter a fancy name for the shortcut and hit finish.

Right click on the just created shortcut and click on the "Shortcut key" field.

Select a convenient letter which you can use with the Ctrl + Alt

Click apply, give permissions then click OK

Done!

From now on every time you want to change profile just hit the keyword combination and the profile manger is there for you.
