clicking on links in external app open Firefox with 2 different windows on Mac Os
I'm a Mac user with Mac Os Big Sur 11.4
When i click on a link in an e-mail on the app "Mail" or in other applications Firefox (89.0.2 64 bits) open the link in 2 different windows : (1 window for the link destination and 1 window for the firefox home page i've set)
I would like to have only 1 window opening when i click on the link.
I've checked on the net and tried the solutions i've found but nothing works...
If i use "Safari" instead of Firefox as my default browser it works properly.
Any idea or suggestions please ?
Thanks a lot for you help.
All the best,
