Firefox Community Forum

Mozilla made an update of my Firefox installation on my Win11 laptop. all my password disappeared as well as my history and bookmarks.

I have now a virgin installation and is starting from scratch.

Now I get this error message: "This profile was last used with a newer version of this application. Please create a new profile." I deleted met shortcut and I opened Firefox by using Windows search. Now I see 4 profiles! I think I do not need to create a new profile. Maybe delete 3 of them ? What to do ? And, how?

With the new profile manager your have to choose a Profile that you have to open on system start. That is okay, but I often change between two main profiles, "Homelab" and Personal. That means if I close Firefox and open it again it defaults to open in the last profile use. When I get an idea, I like to start researching and testing before i get side tracked

Is there a way to specify to open a link in a particular profile, like with Edge you would do something like: "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" -profile-directory="Profile 2"

Thing I have tried:

• "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" -profile-directory="Profile 2"
• C:\Users\%USER\AppData\Local\Mozilla\Firefox\Profiles\vlfrd90t.default
• "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" -P [also -profile] "[Alpha-digits].Profile 1"

Any assistance would be appreciated.
