User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:41.0) Gecko/20100101 Firefox/41.0 Build ID: 20151014143721 Steps to reproduce: 1) open a link from a software 2) open another link from a software Actual results: 1) Firefox is launching, OK 2) Error : Firefox is already running Expected results: When it worked, the second link was openned in a new tab I've tried : - uninstall Firefox and install version 45 - use version 4.1 - upgrade from windows 8.1 to Windows 10 - clean firefox install with ccleaner - clean firefox install with Revo - Manually clean all entry in registry I think the problem began when i tried to define several profiles. I've been searching a solution for 2 months but it seems that Firefox keeps information somewhere about previous installations.

Did you reset the option about Firefox as default browser in Win 10? In addition, open the profile manager ("run > firefox.exe -p") then check your current profile is selected by default and delete the other profiles you don't want to keep. Order of profiles is saved in the file profiles.ini: http://kb.mozillazine.org/Profiles.ini_file
Yes, when i removed Firefox, IE was defined as default browser. I also removed all profiles. But after reinstalling Firefox (a lot of time), it stills no work. I have now only the default profile enabled. It seems that some things of older install can't be deleted. I just want to make a clean install of Firefox expecting it will work well as it was previously : 1) first link clicked launch firefox 2) second link clicked opens a new tab in firefox Thanks
Did you add the command -no-remote to the default profile?
It's a command line option, no ? How can i add this option when clicking a link in thunderbird for example ?
Unfortunately, we don't have enough information here to create actionable next steps. It's possible that windows is misconfigured somehow, or there's a bug that affects your specific install but not most users.
