Developing Firefox or Thunderbird Extensions: Extensions Folder not found in profile folder or Extension not showing up in addons

Issue:
When developing Firefox / Thunderbird Extensions , after copying your extension to the extensions folder, your extension doesn't appear in the Thunderbird / Firefox.

Cause:
Mozilla  apps can be installed under 3 profiles:
1. Single User : Extensions accessible by single user
2. Multi User:  You can setup multiple Firefox profiles still use the same profile folder : default for extensions.
3. Global : This is the installation folder itself. Extensions installed in this folder available for all the users have access to this folder.

If your install option and the development extensions folders  differ , after restarting the application will not be to locate in the extensions folder it is looking for.

FIX:  
(Don't get confused with Window's user profile vs Firefox user profiles - they are different)

 If you had selected 'Single User' install , move your extension files/package  under your user profile
  • Windows: %APPDATA%\Thunderbird\Profiles\<Profile Name>\extensions\ 
  • or
  • C:\Users\<user name>\AppData\Roaming\Thunderbird\Profiles\
    <Profile Name>\extensions\
 If you installed as Global, move your extension files/package  to

 C:\Program Files (x86)\Mozilla Thunderbird\extensions

Once you put your development Firefox / Thunderbird application in the right extensions folder, restart Firefox / Thunderbird. Now you will see this below alert message.

Another program on your computer would like to modify Thunderbird with the following add-on

Allow this installation

You must restart Thunderbird to finish installing  this add-on.

Will Software engineer salary hit $1 million by year 2030

Are today’s Developers over loaded with too many tasks?! In 90s and till late 2000s there were many different job positions in an IT team that only do certain task.
