Windows 10: Info on setting up Gmail as the default using Firefox?

I am looking to configure W10 Pro 1809 to use Gmail as the default mailbox, opened in Firefox which is already the default browser.
The are numerous web articles but their instructions refer to menu objects that were renamed and moved. So, I got nowhere.
Can anyone please point me towards some up to-date info, and I shall be on my way.

Set Firefox/gmail as my default mail client


Clicking on an mailto link in Excel or Word no longer brings me to Firefox and gmail. I have Windows 10. My default browser is set to Firefox. Website hyperlinks in Excel or Word work fine, taking me to Firefox. Within Firefox the mailto is set to gmail and this works if I am in Firefox.
Under Windows/Control panel/Default apps/email Firefox is not listed as an option.
Any ideas?

 

How to set Firefox (Gmail) as Windows' default service for email links

Of course GMail is not a program. And this is why OutlookCalendarScroll was asking "How to set
Firefox as Windows' default for email", and why we are talking mostly about Firefox, and not about Gmail here. The webservice you choose in Firefox doesn't change in any way my solution. We are talking here about how can we force Windows 10
to open all email links with Firefox. The manner Firefox reacts to these links well that's another story (Story i mentionned in "NB" section, but here we are in a Microsoft forum, so i don't want to develop more on this point, there is all informations you
need on this point here :
https://support.mozilla.org/fr/products/firefox).

And sure, you need to have Firefox installed on your computer if you want to launch Firefox on your computer...

Wrong, wrong, wrong. We're talking about setting the Gmail web service as the default mail client, which you acknowledge can't be done. Having the "send to" or "Mail to" prompts open Firefox doesn't address the issue. Even if one has Firefox
set to open Gmail when it starts it won't accomplish such things as placing attachments in an email message, which can be done if a proper email client is set as the Windows default.
