Peter, thanks.

I do not have Preferences | Message View | Web Browser.
Instead I have Preferences | Message View | External Programs.

Then under that I have (without the <> marks):
 
<Use system defaults when possible>
<Web browser  firefox '%s'>
<Text editor  gedit %s>

Please note that the tick box under <Use system defaults> is ticked.
If I untick it the dropdown then shows <firefox  '%s'> instead of
<xdg-open %s> and no brower opens.

The preferred browser application selected for Mint 20.2 shows:
<Firefox Web Browser> 

Thanks.
Gil
